Boron carbide is a hard, black crystal with metallic luster, which is also known as black diamond. It is a kind of powder that is obtained after smelting between boric acid and carbon in the electric furnace with high temperature and then crushing. It can resist high temperature, acid and alkali corrosion. Furthermore, it has high intensity, stable chemical performance and small proportion. It belongs to the high-tech industry and is widely applicable to machinery, petroleum, chemical engineering, shipbuilding, metallurgy, automobile, aerospace, military project, atomic energy and other industrial fields. Boron carbide has blast nozzle, sealing ring, drawing die, mould, sliding plate, measuring head, bearing, body armor, armor plate and neutron absorption block. It is widely used in jet, sealing, drawing, casting, protection, corrosion resistance, measuring and other technical fields, and greatly promotes the development of above industrial areas. Nowadays, the developed countries in the world are using boron carbide as abrasive material to replace hard alloy and alumina. Our company can process or produce various shapes and specifications of ceramics in boron carbide project according to the requirements of users
1、碳化硼——高级耐火材料必不可少
Boron carbide – is essential for high - quality refractories
由于碳化硼具有抗氧化、耐高温的特性，被用作高级的定形和不定形耐火材料广泛用在冶金各个领域，作为抗氧化剂、填充剂被广泛使用于镁碳砖、铁钩浇注料等主材中,在钢铁工业中用于耐高温、耐冲刷的关键部位。如钢包、出铁口（水口）、滑板、塞棒、钢铁炉具、窑具等。
碳化硼在含碳耐火材料中起抗氧化作用,可以使产品致密化阻止含碳耐火材料中碳的氧化,同时在1000℃~1250℃发生反应，生成（9AL2O3•2B2O3）柱状晶体分布在耐火材料的基质和间隙里，从而降低气孔率，提高中温强度，且生成晶体体积膨胀，可愈合体积收缩，减少裂纹。
Due to oxidation resistance and high temperature resistance, boron carbide is widely used in metallurgy as a kind of high-quality shaped and monolithic refractory material. As an antioxidant and filler, it is widely used in principal materials such as magnesia carbon brick and castable of iron trough, and is utilized as a key part of high temperature resistance and erosion resistance in the steel industry, including ladle, nozzle, sliding plate, stopper, furnace and kiln.
As for carbon-based refractories, boron carbide is an important antioxidant and can prevent oxidation of carbon. At the same time, with the temperature between 1,000 degrees Celsius and1,250 degrees Celsius, chemical reaction happens and then 9AL2O3•2B2O3 is generated, which scatters in the matrix and gap of refractories. As a result,the porosity is decreased, the intensity of medium temperature is improved, the volume of generated crystal is expanded, the volume of coalescence is shrunk and the crack is reduced.
