Audited Supplier Chemical Name:Boron Powder
CAS No.:7440-42-8
Molecular Formula:
Molecular weight: 10.81
Appearance: Brown powder or black powder
Boron is a non-metallic chemical element with an atomic number of 5, which is a black or silver-gray solid with the element symbol B. The hardness of crystal boron is second only to diamond, and the texture is brittle.
Boron is a widely used chemical raw material mineral, [1] mainly used in the production of borax, boric acid and boron compounds and element boron, is an important raw material in metallurgy, building materials, machinery, electrical appliances, chemical industry, light wool, medicine, agriculture and other fields.
1. Boron fiber has high strength (breaking strength at room temperature is 2744 ~ 3430MPa) and high modulus of elasticity (39200 ~ 411600MPa), which is an excellent reinforcing material.
2. Composite materials made of boron fiber with metal (aluminum, magnesium, titanium, etc.), various resins (epoxy resin, polyamide, etc.) and ceramics are excellent high-temperature structure materials.
3. Reinforcement ceramics made of titanium boride have excellent abrasive resistance and high toughness (up to 10 MPa·m 1/2 or more), which are used to manufacture conductive parts for heating equipment and ignition devices.
4. Used as a deaerator in the metallurgical industry and an additive to improve the structure of metal grains.
5. Boron-cast iron is widely used in automobile, tractor, machine tool and other manufacturing industries.
