Parameters of The Ceramic Materials Used for Ballistic Armor Plates silicon carbide (sic) Boron Carbide
Silicon carbide ( sic ) is a heat-resistant material commonly used in ballistic armor plates. It is made from sand, and when mixed with carbon dioxide gas and treated with high temperature, it can form a hard, wear-resistant ceramic material.
The boron carbide parameter of Silicon carbide refers to its hardness, which is determined by measuring the coefficient of thermal expansion (CTE) of the material under pressure. A lower CTE indicates that the material is harder and more resistant to changes in shape and size.
In the context of ballistic armor plates, a low CTE allows the material to withstand significant temperatures without degrading significantly. This makes it an ideal material for use in high-temperature environments such as those found in aircraft or armored vehicles.
It’s worth noting that while Silicon carbide is known for its high strength-to-weight ratio, it can also be difficult to work with in certain applications due to its high melting point and brittleness. In general, Silicon carbide is considered one of the most effective materials for use in military armor and other applications where extreme durability and resistance to deformation are important.
