Executive standard: Q/YTY002-2022. Physical and chemical properties： Elementary symbol: B, Atomic weight: 10.81 (on 1979 international atomic weight), Melting point: 2300±2℃, Sublimation temperature: 2550℃, Density: 2.34-2.37 g/cm3. Solubility: Insoluble in water, ethanol, ethyl ether, and hydrochloric acid. Dissolved in cold concentrated basic solution and produced H2 at the same time. It can be oxidized by concentrated sulfuric acid or nitric acid and produce boric acid. Properties: It is tasteless and odorless. Boron is between the metal element series and the non-metal element series in the periodic table of elements. Boron has many characteristics, such as strong electronegative, low atomic radius, and centralized nuclear charge. Therefore, the chemical properties of boron are relatively active. The non-metal property of boron is similar to that of silicon.
Boron can react with oxygen, nitrogen, sulfur, halogen, or carbon at high temperatures. Boron is stable at normal temperatures, but it will be oxidized when heated to 300℃ and burned if heated to 700℃. Boron can be combined directly with many metals to form metal boride. Application: Boron has been used mainly in metallurgy, electronics, medicine, ceramics, the nuclear industry, and the chemical industry, etc. Boron has also been used in compounds or as an additive in alloys. In addition, it can be used as the gas scavenger in the metallurgy of some special alloys and smelted steels, the ignitor in the electric industry, the control rod of atomic reactors, and the high-energy fuels for solid rockets. Boron is an important raw material for manufacturing high-purity halogenated boron and various borides. Some rare noble metals can be substituted by boron. Boron and its compounds can also be used as the catalysts of some organic chemical reactions.
