product description
Boron is a chemical element; It has the symbol B and atomic number 5. In its crystal form, it is fragile, black, glossy, and metallic like; In its amorphous form, it is a brown powder. As the lightest element on Earth, the boron group has three valence electrons used to form covalent bonds, producing many compounds such as boric acid, superhard crystals of mineral borax, boron carbide, and boron nitride
Boron is mainly used in compounds. About half of all products consumed globally are additive glass fibers used for insulation and structural materials. The next main application is in high-strength, lightweight structures, and heat-resistant materials for polymers and ceramics.
Borosilicate glass has higher strength and thermal shock resistance than ordinary soda lime glass. Like sodium perborate, it is used as a bleaching agent. A small amount is used as a dopant in semiconductors, as well as in the synthesis of organic fine chemicals as reagent intermediates. Some boron containing organic drugs are currently in use or under research. Natural boron is composed of two stable isotopes, one of which (boron-11) has many uses as a neutron capture agent.
