(2) It is used for grinding carbide, precious stones and other hard materials, grinding, drilling and polishing, metal boride manufacturing and smelting boron steel, boron alloys and special welding. Abrasive. In the manufacture of hard and chemicals-resistant ceramics or wear-resistant tools. Finely pulverized B4C can be molded under (considerable) pressure and heat. Boron carbide (B4C) is a hard, black crystal that is used as an abrasive powder and as an additive to strengthen composite parts in aircraft. Boron carbide is a hard boron-carbon ceramic material used in tank armor, bulletproof vests, engine sabotage powders, neutron absorber, cutting tools and dies and in brake linings of vehicles. It acts as an antioxidant additives in magnesia-carbon bricks. It is used as a precursor in the production of boron containing materials such as titanium boride.
• Description: Sodium tetraborate decahydrate/borax (anhydrous) is a clear, colorless or pale yellow hygroscopic substance with a faint odor of detergent. It is stable and is incompatible with powdered metalsand slightly soluble in water. It is extensively used in the industrial manufacturing of metallurgical fluxes, fiberglass, ceramics, fertilizers, enamels, heat-resistant glass (e.g., Pyrex), and other chemicals. It decomposes on heating or on burning producing toxic fumes including sodium oxide, reacts with strong oxidants, and in fire gives off irritating or toxic fumes (or gases).
• Physical properties: Black hard crystal; density 2.50 g/cm3; hardness 9.3 Mohs; melts at 2,350°C; vaporizes above 3,500°C; insoluble in water and acid; inert to most chemicals at ordinary temperatures; rapidly attacked by hot alkalies.
