CAS 7440-42-8
25kgs/bag,20tons/20'container



CAS 7440-42-8 is a black or dark brown powder. When it is oxidized in the air, it will prevent the internal boron from continuing to oxidize due to the formation of a boron trioxide film. It can react at normal temperature Amorphous Boron Powder is insoluble in water, powdered boron is soluble in boiling and most molten metals such as copper, iron, manganese, aluminum, and calcium.

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.

Boron is an extremely valuable mineral and it is used in many products from cookware and medicine to nuclear waste storage and space exploration. Boron compounds are mainly used in borosilicate glass products, but are also used in agriculture, in fire retardants, and in soaps and detergents.
Boron is used in special-purpose alloys, in cementation of iron, as oxygen scavenger for copper and other metals, as fibres and filaments in composites with metals or ceramics, as semiconductor, for nuclear reactors, as a shield for nuclear radiation and in instruments used for detecting neutrons. Boron is used in pyrotechnic flares (distinctive green colour), for rockets (as an igniter), in boron-coated tungsten wires and in high temperature brazing alloys.

Boron tribromide 2nb-6nb

Uses: boron tribromide is used as catalyst, intermediate and brominating agent in organic synthesis and is the raw material of making high-purity boron powder and other organoboron compound. It is also used as the dopant source of the semiconductor silicon and is used to make the high-purity boron and the organoboron compound.
