Details Introduction
1. molecular formula: BBr3
2. molecular weight: 250.5
3. physical and chemical properties
Boron tribromide has a strong pungent odor and is a colorless or slightly yellow fuming liquid at room temperature. Density 2.65 g/mL(20 ℃), melting point -46 ℃, boiling point 91.7 ℃ (standard atmospheric pressure). Soluble in carbon tetrachloride, strong water absorption, easy to be water and alcohol decomposition. It is easy to decompose when exposed to light and heat, and may explode when heated, and white smoke will be emitted when exposed to air. It is a strong Lewis acid that reacts with bases to form complexes and adducts. It has a strong stimulating effect on people, strong corrosiveness, and toxic vapor.
4. uses
Electronic grade boron tribromide is used in semiconductor integrated circuits, solar cells, semiconductor separation devices and other industries as a P-type doping source to p-type doping of crystalline silicon through thermal diffusion. Secondly, boron tribromide is also a raw material for the manufacture of high purity boron and other organic borides.
