Boron carbide is one of the raw materials of multiphase ultra-hard and ultra-high temperature ceramics. It has higher heat resistance and chemical reaction resistance than steel. It is used to make high-temperature devices.

High performance structural ceramics made of boron carbide are better than steel alloy materials in fatigue strength and corrosion resistance. High strength ceramics can be used in burners, blades, bushings of gas turbines and bed, bearings, nozzles of machining machines.
