Chapter 116 Isotopes?

In fact, Zhang Hao has a little guess about Xuan Tie:

isotope!

Both black iron and iron exist in the ore in the form of iron oxide, so during the ore screening process, it is impossible to distinguish between black iron and iron.

During the smelting process, charcoal is needed for reduction. In an environment without aura, both can be oxidized to rust, making it difficult to distinguish each other.

Besides, the magnetism, some of the chemistry, are exactly the same.

What is commendable is that the most excellent dark iron purified by the Zhang family, which is 99.9% black iron density, is just about one-fiftieth more than the rough iron!

All of this seems to point to an isotope of iron: iron 57!

Of course, the molecular weight of 57 is based on the standards of another world; anyway, Zhang Hao remembers that the textbook said that the molecular weight of iron is usually 56, and there are isotopes such as iron 54 and iron 57 in nature.

And the 'black iron' here happens to be a bit heavier, and it is very likely that it is Iron 57.

Iron 57 has one more neutron than iron 56!

In other worlds, it is said that 'neutrons' have no attributes; scientific research is mostly carried out around electrons and protons.

Perhaps, neutrons are not without attributes, but because another world has no aura, neutrons are redundant. But with the aura in this world, the importance of neutrons is revealed!

Zhang Hao returned to his room, took out a notebook, and began to write and draw:

If this conjecture is correct, then Zhang Hao also has a little guess about the nature and function of the abnormal fire and the real fire - to stimulate the aura and let the neutrons capture the aura!

To test this idea, it is relatively simple in principle. According to ordinary observations, if you want to 'stimulate aura', the temperature of ordinary flames is far from enough, so you need to use some kind of strange fire or real fire.

And the easiest way to get high temperature is 'high pressure'. The representative product is: pressure cooker.

Of course, if one wants to obtain a temperature far exceeding that of an ordinary flame, the pressure must be extraordinary.

According to the usual smelting data, this temperature must exceed, or even far exceed, two thousand degrees. And more than 2,000 degrees is enough to melt the black iron.

Then, it is necessary to look for tungsten ore or graphite. But with Zhang's current weak technology, graphite is the first choice.

No... wait, this is the practice world, there are formations! I don't know if using the array method can meet the requirements?

After lunch, Zhang Hao found his father and asked about the formation.

"A formation that is airtight, can withstand high temperature and high pressure, and has a large enough area?" Zhang Shengde thought for a while and said, "There are such formations. The formation that seals the ground fire in our smelting base should be .

That formation is called... by the way, it's called Sleepy Dragon Formation, yes, it's called Sleepy Dragon Formation. "

"Father, you can't even name our own formation?"

"Bastard!" Zhang Shengde slapped Zhang Hao on the head, but it was useless. "The formation was helped by others, how can I remember it clearly. By the way, the formation was arranged by your uncle."

"Then what about my uncle?" Zhang Hao was very curious. He had never seen anyone from his mother's side, as if he had evaporated out of thin air. Could it be some bloody plot?

Zhang Shengde's face was a little weird: "Your uncle...can't comment. The last time I saw him was more than 20 years ago. He is a master of formations, and his cultivation has reached the peak of the Golden Core stage.

But he likes to travel around, saying that he wants to find an opportunity to break through to the Nascent Soul Stage. Leaving your mother behind, after arranging the formation, they floated away.

So far no more audio. "

Zhang Hao frowned suddenly, feeling...another very unreliable guy!

"In these years, your mother has cried several times. But the world is vast, where can I find it. Hey..."

"What about my grandma and grandpa?"

"When I met your mother, it was only your mother and your uncle. At that time, your mother was just 16 years old."

…………

In the afternoon, Zhang Hao came to the conference room of the Refining Guild.

Zhou Jue greeted Zhang Hao enthusiastically, "Brother Shi, sit here."

Zhou Jue asked Zhang Hao to sit in the seat of the vice chairman. Originally the vice chairman belonged to Zhang Shengye, but now Zhang Shengye is very injured and not in a good mood, so...absent.

Zhang Hao greeted everyone. Compared with the Black Iron Guild, the atmosphere of the Artifact Refining Guild was more harmonious.

No, Zhang Hao hasn't sat down yet, Mei Qianyun chuckled and said, "Zhang Hao, just now Zhou Jue said that you have the habit of sleeping late?"

There was good-natured laughter all around.

Zhang Hao sat down with a dark face and dejected, but saw in front of Zhou Jue, there was a piece of irregular silver-white metal the size of a child's fist. .

"Is this... star gold?"

Zhou Jue nodded: "It was sent by Ouchi's guards. It weighs more than 25 kilograms. This thing has almost three times the weight of black iron."

"Can I see it?"

Zhou Jue nodded. Zhang Hao took it over and tried it, and by the way, used his immature identification technique to make an identification; the metal, the size of a child's fist, weighs 25 kilograms, and its density is roughly 3.5 times that of black iron.

Zhang Hao's eyes narrowed: metals from space have a density almost 3.5 times that of iron, and exist in the form of simple substances. Could this be... iridium?

And remember that on the periodic table, iridium seems to have a molecular weight of 192 and an atomic number of 77. That is to say, iridium has 115 neutrons, and the number of neutrons far exceeds that of protons!

If this thing is really iridium, then Zhang Hao can conclude that there must be a relationship between aura and neutrons.

Zhang Hao put down the star gold calmly, and praised it by the way.

A few more people came after a while, and Zhou Jue clapped his hands: "The meeting has begun. Today we are going to discuss the management model, determine the various departments and persons in charge, and a new production method."

The meeting lasted until the evening, especially when it came to new production methods, division of labor, streamlined operations and other issues, Zhang Hao showed off a little.

At the end of the meeting, Zhang Hao got up suddenly, "Wait a minute, everyone. I want to buy a set of array flags or disks for the trapped dragon array. It should be able to withstand high temperature, high pressure, and airtight."

Mei Qianyun was the first to speak: "What you want is an airtight formation that can withstand high temperature and high pressure?"

"right."

"Our Yuxue Villa has a set of 'Mountain Binding Formation', and the complete Binding Mountain Formation can even seal volcanoes."

Zhang Hao was overjoyed: "Come here! Simple ones are fine."

Mei Qianyun laughed immediately: "A simple mountain-binding formation requires...a ton of black iron for alchemy!"

Zhang Hao's face turned dark immediately: "Mei Xianzi, we are all acquaintances, let me give you a real price. You quote Lingshi, and I will give you Xuantie."

Mei Qianyun smiled triumphantly: "Zhang Hao, do you know how complicated a set of mountain-binding formations is? Even if it is simple, there are one hundred and eight formation flags. It is enough to make the Zhang family suffocate and trap the Nascent Soul stage!"

Zhang Hao's eyes lit up: Ha, have you thought about this? Well, Zhang Hao agreed straight away, and asked for the manual—a jade slip.

"Tomorrow, the formation flag will be delivered. The Zhang family must prepare the black iron."

"Xuan Tie needs a little time. How about ten days?"

"it is good!"

As soon as Mei Qianyun finished speaking, Mu Yingying immediately grabbed the conversation: "We have a complete trapped dragon formation at home, and the effect is very good. As long as a thousand high-grade spirit stones are enough."

"I want two sets! We will pay with black iron for alchemy." Zhang Hao opened his mouth loudly.

"Okay!" It was Mu Mingchen who answered.

Zhou Jue finally had a chance: "Brother Shi, our Nine Suns Sect has a more powerful 'Hundred Immortal Formation', similar to the Sleepy Dragon Formation, but several times stronger."

"Then make another set! Also pay with the special black iron for alchemy."

Zhou Jue was not polite: "One ton."

"Yes." Zhang Hao said simply, "But isn't the price a bit high?"

"Don't worry Shidi, if you find out that the price is too expensive in the future, we will refund it all!"

Zhang Hao smiled and turned to look at everyone: "Anyone who has a similar formation is welcome to provide it. The Zhang family will pay with black iron for alchemy. It will be paid at cost price, only this time!"

"Master Zhang, we have a set of 'Zhou Tianfeng Demon Formation'."

"We have the 'Great Zhou Tianfeng Demon Formation' and the 'Eight Directions Demon Refining Formation'."

"We have the 'Monster Refining Formation'!"

"We have……"
