Boron carbide uses

Recently, covid 19 outbreak spreads in Shanghai, China. There are more than 25,000 new asymptomatic domestic infections every day. China is implementing a dynamic zero-out policy. A leading respiratory expert said the key to COVID-19 prevention and control is to minimize transmission and fatality rate. Omicron has a low case fatality rate but is highly transmissible and can still claim many lives in large outbreaks. "Total openness is not applicable in China.  For China, we should keep to the dynamic zero-out and gradually open up."  

However, "dynamic zero clearance" is not the pursuit of complete "zero infection".  As the Novel Coronavirus has its own uniqueness and strong concealment, there may be no way to prevent the detection of cases at present, but rapid detection and prompt treatment must be carried out, as soon as one case is found, one case will be dealt with.  

The situation in Shanghai is serious. As the financial center of China, Shanghai is a very important city, and the outbreak of the epidemic in Shanghai will put a great impact on China's economy.  The current task is to contain the spread of the epidemic as soon as possible, to achieve social zero so that Shanghai's life and economy quickly return to normal.  

As China plays an important role in the global supply chain, the outbreak will have a significant impact on the supply and prices of many boron carbide.

What is Boron carbide?
Boron carbide (B4C) is also called black diamond. It is grayish black, and is a very hard man-made material: Its Morse hardness scale is 9.3, microhardness is 5500~6700kg/mm2, second only to diamond and cubic boron nitride.
Boron carbide structure is hexagonal crystal. Boron carbide density is 2.52g/cm3. Boron carbide melting point is 2450℃, and it decomposes and volatilizes rapidly when the temperature is higher than 2800℃.
 
Boron carbide properties
Boron carbide is insoluble in water and organic solvents, has strong chemical stability, is resistant to acid and alkali corrosion, and does not react with almost all acid and alkali solutions. Boron carbide has large thermal neutron capture cross section and strong neutron absorption capacity, so it is called neutron absorber and semiconductive.
 
What are the advantages of boron carbide?
High hardness.
Low density.
High melting point.
High elastic modulus.
Chemical inertia.
High neutron absorption cross section.
Excellent thermoelectric performance.
 
Boron carbide uses
Because of its attractive combination of characteristics, it is a suitable material for many high-performance applications.
The excellent hardness of boron carbide makes it a suitable grinding powder for grinding, polishing and water jet cutting of metals and ceramics. It is suitable for grinding, polishing, drilling and other processing of all kinds of cemented carbide tools, moulds, parts, components and gemstones. Boron carbide can be made into grinding paste and polishing paste with appropriate amount of oil or water as lubricant.
 
The combination of low specific gravity, high hardness and reasonable toughness makes it a suitable material for car body and vehicle armor.
Boron carbide is also widely used as control rods, shielding materials and neutron detectors in nuclear reactors because it can absorb neutrons without forming long-lived radionuclides.
Because it is a p-type semiconductor, boron carbide can be a suitable candidate for electronic devices that can work at high temperatures.
Boron carbide is also an excellent p-type thermoelectric material.
 
Some typical boron carbide applications include:
Sandblasting nozzle.
Ball and roller bearings.
Sealing parts.
Wire drawing die.
Bulletproof vest

"Is there talk of solidarity with Sweden and Finland joining NATO? No." "So is the West united?" Zelensky said at this Ukraine-hosted breakfast in Davos. No." "Our strength is unity within the country," Zelensky said. "Now it depends on the Unity of the West to stand strong and firm behind Ukraine against Russia.

According to Zelensky, "When we are all really united, we will have an advantage over Russia."  

Ukrainian President Volodymyr Zelensky says he once again appreciates U.S. President Joe Biden's offer of $40 billion in new financial aid to Ukraine.  

"We need the support of a united Europe," Zelensky stressed. Zelensky criticized the position of Hungarian Prime Minister Viktor Orban, who is reluctant to impose an embargo on Russian oil at this stage. "Hungary has a problem!" Zelensky criticized.

The supply and prices of many other boron carbide are expected to continue to be influenced by changing international situations.
