Application of calcium hexaborate
Calcium hexaboride is a black solid. Hardness 9. Relative density 2.33, melting point 2373-K. It is stable in the air at high temperatures. Insoluble in hydrochloric acid, hydrofluoric acid, and dilute sulfuric acid. Does not react with water. It can be eroded by strong oxidants such as chlorine, fluorine, nitric acid, and hydrogen peroxide, and reacts slowly with alkali. At room temperature, there can be three states, powder, single crystal, and polycrystalline. Due to the characteristics of high melting point, high strength, and high chemical stability of calcium hexaboride, many of them also have special functions, such as low electronic work function, constant specific resistance, zero thermal expansion value within a certain temperature range, different types of magnetic order, and high neutron absorption coefficient. These superior properties determine their broad application prospects in various device components of modern technology. At the same time, due to the characteristics of the connection structure between boron and calcium atoms in calcium borate, it has a high melting point, specific conductivity, and excellent electromagnetic radiation protection performance. Used as a boron-containing additive for oxidation resistance, corrosion resistance, and improvement of thermal strength of dolomite carbon and magnesium dolomite carbon refractories; 2. Used as a new type of neutron shielding material for the nuclear industry, as a raw material for the manufacture of high-purity metal borides (TiB2, ZrB2, HfB2, etc.), and high-purity boron alloys (Ni-B, Co-B, Cu-B, etc.); 3. Used as a catalyst mixture containing calcium boron nitride (Ca3B2N4) and hexagonal nitride and as a raw material for producing crystalline cubic boron nitride with excellent performance; 4. Used as a deoxidizer to enhance the strength of high-conductivity copper; 5. Used as a new semiconductor material for spin electron modules at a temperature of 900 K; 6. Used as a desulfurized, deoxidizer, and bronzer for boron alloys; 7. Used in the manufacture of amorphous boron and boron trichloride (BCl3) and used in the nuclear industry as neutron absorbing materials, deoxidizers for the copper smelting industry, doping sources for electronic industry components, and additives for refractory materials. Currently, the research and application of calcium hexaboride ceramics have rapidly developed. The dosage forms of products are no longer limited to powder products, and polycrystalline products are increasingly becoming popularMaturity increasingly provides a new field of application for calcium hexaboride to meet the development of new materials.
