Some nanomaterials for Thermochromic Application
Thermochromism refers to the phenomenon where a material undergoes color changes under temperature changes. This change is usually caused by changes in the electronic or molecular structure of the material. Its application principle mainly involves t...
Boron carbide, also known as black diamond, has a molecular formula of B₄C, usually gray-black powder. It is one of the three hardest materials known (the other two are diamond and cubic boron nitride). It is used in tank armor, bulletproof vests and many industrial applications. Its Mohs hardness is 9.3. Because of its low density, high strength, high temperature stability and good chemical stability. It is used in wear-resistant materials, ceramic reinforcing phases, especially in lightweight armor, reactor neutron absorbers, etc.

Boron carbide is a new type of non-oxide ceramic material. Because of its high melting point, high hardness, low density, good thermal stability, strong chemical resistance and strong neutron absorption ability, it is used in the national defense and military industry. It plays an important role in the maintenance of safety.
Ultra-fine boron carbide powder can be sintered into boron carbide ceramics. In theory, the smaller the particle size of the boron carbide powder, the better the density of the boron carbide ceramic sintered.
The high melting point, high hardness and low density of boron carbide ceramics make it an ideal substitute for ballistic material applications. At present, boron carbide bulletproof materials have been widely used in the protection fields of body armor, bulletproof armor, armed helicopters, etc.
Among the reactor core components, neutron absorbing materials (control rods, regulating rods, accident rods, safety rods) are important functional components second only to fuel elements. Due to the high neutron absorption cross-section of boron carbide and the wide absorption energy spectrum, The price is low and the source of raw materials is abundant, which makes it easy to dispose of waste. Therefore, boron carbide is an important neutron absorbing material.
