Boron nitride ceramic is primarily produced from boron carbide powder, which, after being shaped and sintered to achieve a stable crystalline structure, exhibits properties such as heat resistance, hardness, wear resistance, corrosion resistance, light weight, thermal shock resistance, and oxidation resistance. Due to these qualities, it is utilized extensively in various industries including mechanical engineering, semiconductors, petrochemicals, electric power, environmental protection, energy conservation, and national defense. Depending on its composition and sintering method, boron carbide ceramics can be categorized as pressureless sintered, hot pressure sintered, HIP sintered, among others, allowing for the selection of the appropriate type based on specific application needs and parameters.
