Vol 2 Chapter 892: Nuclear weapons program phase 4

The genius remembers the address of this site for one second: (Vertex Chinese), the fastest update! No ads! "Other?" asked the old lich Afu.
"Yes, others." Richard nodded. "Besides what I have said, one thing to consider is that in some cases, private forces will react to individuals.
If the starting point for the development of private power is to help yourself, then after development, it will definitely allow private power to provide itself with certain services and be responsible for what it has done. Let’s not talk about how well the private forces are doing. It is undeniable that if something goes wrong with the other party, it will greatly affect yourself.
The larger the private power, the more prone to various problems. Even if you invest a lot of energy to avoid it, you may be deliberately attacked by the enemy because of the struggle for certain interests. "
"So, you will never develop private power?" The old lich frowned. "You can't always say that private power is useless?"
"Of course not." Li Cha shook his head. "I understand that sometimes, the role of private forces cannot be ignored, and it can act as a multiplier, shortening the distance that I have to achieve success. I will eventually develop private The forces will even develop on a large scale, but before that, I chose to take the research route."
"Research route, what is this?"
"The simple explanation is that I am exploring this world and want to clarify something. Only by the end of the exploration can I be sure that I really need to use private power to help me do.
For example, a few years ago, I might just use them to help me prepare some simple chemical agents. Now, I might ask them to help me purify the uranium element. After that, it might be possible for them to use the exhaustive method. Analyze some rules.
The goal of a private force largely determines the positioning of a private force, which will affect its structure, quality of personnel, and number of personnel.
At present, I can handle many things. It is helpful to build a private force, but it is not necessary. Only when it is really necessary, I will create, for example, in my research, I have reached a bottleneck that some individuals cannot break through, and I will try to create private forces to force break through the bottleneck.
All in all, in short, I haven't reached the time yet, that is, I occasionally plant a few seeds, or create a loose business organization to serve myself by smashing money. Only at the critical moment will I invest a lot of energy. "
"So!" The old Lich listened, his eyes widened a little, and he said irritably, "So, you can call me back with peace of mind and fight for you, right? You want to save energy and don't blindly build private forces , But unkindly squeezed me and occupied my time, which was not in our previous agreement."
"It doesn't blame me." Li Cha spread his hand. "I didn't intend to trouble you, but before the mine happened, you clearly told me'let me handle it casually', what can I do?"
"This--" The old Lich expression stiffened and said nothing, because Richard was telling the truth.
After being silent for a long time, the old lich stepped forward and sat back heavily on the easy chair next to him, angrily said, "I can afford to do it. But after all, even if I do, I should help you. Let’s take a break. I’m an old man. I don’t know the real age. I don’t know if I’m a hundred years old. Is it okay for me to take a break? I’ve decided, I’ll lie down and help you again.

"Just be happy," Richard said, shaking his head slightly and stepping aside.
Now, there is indeed no need to let the old Lich do the work.
The old Lich watched Li Cha go away, Shu spread his body, lay on the easy chair with his eyes closed, "creeped" a few times, and uttered: "Comfortable." Enjoy the few leisurely moments.
On the other side, Li Cha walked to the end of a row of chemical instruments, glanced at the instruments, and then began to adjust with the joystick.
A few minutes later, accompanied by a burst of "guichi" sound, a special glass container over one meter high began to produce matter.
It was a colorless and transparent particle, a bit like salt.
However, Richard is clear that in a sense, this is even more dangerous than the most dangerous salt grain he has ever made-spell salt.
Because the other party's name is called uranium hexafluoride, the chemical formula UF6 is a substance produced by the combination of six fluorine elements and one uranium element, and it is also the product of the third stage of uranium element purification.
To get the other party, the yellow cake (U3O8) obtained in the previous stage needs to be ion-exchanged to remove the impurities that absorb neutrons in the uranium salt, and ensure that the impurity content does not exceed the equivalent equivalent of 8 parts per million boron (ie 100 Of ten thousand parts of uranium, eight parts of boron absorb slow neutrons).
After that, the metal elements iron, aluminum, nickel, etc., which may generate non-volatile fluorides, are removed, and high-purity uranium oxide-uranium dioxide (UO2) is generated.
Then the black powder of uranium dioxide (UO2) ~EbookFREE.me~ reacts with hydrofluoric acid (HF).
Hydrofluoric acid (HF) is an aqueous solution of hydrogen fluoride, known as bone erosion water, bone ossification water, and osseous acid, and is highly corrosive. Because of its relatively strong ability to bind between hydrogen and fluorine atoms, it cannot be fully ionized in water. In theory, it is only a weak acid, but it can dissolve many substances that other strong acids cannot dissolve, such as ruthenium, rhodium, tantalum, etc. .
It forms uranium tetrafluoride (UF4) with uranium dioxide (UO2).
Uranium tetrafluoride undergoes an oxidation reaction with fluorine, which ultimately produces uranium hexafluoride (UF6).
As a raw material for nuclear weapons that is further than the yellow cake, UF6 has many special properties.
For example, its melting point is 64.8°C (338.0K), but its boiling point is lower, at 56.5°C (329.7K).
This leads to it being originally solid. When the temperature reaches 64.8°C, it can be directly transformed into a gas without the process of melting into a liquid, which is called sublimation.
In addition, it is very toxic, and it is necessary to avoid direct contact with the human body. It can also react violently with water and can corrode most metals, so the best way to store it is with a gas steel tank.
Richard looked at the meter and determined that the temperature in the product container was 35°C, the air was zero, and the moisture was zero, so rest assured. Afterwards, all the produced UF6 was packed into gas steel tanks and put in storage.
This is the third phase of the nuclear weapons research and manufacturing program.
Then the next stage is the fourth stage-the final purification of uranium.
In a sense, this is also the only true purification, because the object it faces is no longer a wide range of uranium elements, but more precise uranium 235.
Yes, uranium 235.
