What material is boron carbide?
Boron carbide is produced by smelting boric acid and carbon materials at high temperatures in an electric furnace. Its theoretical density is 2.52g/cm3, its melting point is 2450°C, and its microscopic thickness is 4950kgf/mm2. Its high degree of sintered diamond and cubic boron has the characteristics of high temperature resistance, acid and alkali corrosion resistance, high strength, high chemical stability, and light specific gravity, making it an ideal material for the livestock industry.
1. The most important performance of boron carbide is its extraordinary hardness (Mohs hardness is 9.3). Starting from diamond and cubic boron, it is the most ideal high-temperature wear-resistant material;
2. The density of boron carbide is the lightest among ceramic materials and can be used in the aerospace field;
3. Boron carbide has great neutron absorption capacity. Compared with pure elements B and Cd, it has low cost, good corrosion resistance and good thermal stability. It is widely used in the nuclear industry. The neutron absorption capacity of boron carbide can also be improved by Further improvements are made by adding B elements;
4. Boron carbide has excellent chemical properties. It does not react with acids, alkalis and most inorganic compounds at room temperature. It corrodes slowly in mixtures of hydrofluoric acid-sulfuric acid and hydrofluoric acid-nitric acid. It is the most stable chemical compound. one;
5. Boron carbide also has the advantages of high melting point, high elastic modulus, low expansion coefficient and good oxygen absorption capacity;
6. Boron carbide is also a p-type semiconductor material and can maintain semiconductor properties even at very high temperatures.
