Boron oxide may refer to one of several oxides of boron: Boron trioxide (B 2 O 3, diboron trioxide), the most common form; Boron monoxide (BO) Boron suboxide (B 6 O)
Boron trioxide or diboron trioxide is the oxide of boron with the formula B 2 O 3. It is a colorless transparent solid, almost always glassy (amorphous), which can be crystallized only with great difficulty.
Its color ranges from black to brown and gold, depending on the chemical bond. It is one of the hardest known materials, along with various forms of diamond and other kinds of boron nitride. Borazon is a crystal created by heating equal quantities of boron and nitrogen at temperatures greater than 1800 °C (3300 °F) at 7 GPa (1 million lbf/in 2).
One of its uses is as a binder in some grades of hexagonal boron nitride for hot pressing. Other uses include flame retardant in epoxy molding compounds, a ceramic flux in some ceramic glazes, reactive self-sealing binders in hazardous waste management, [1] additive for insect-resistant polystyrene, [2] fertilizer, and production of boron glasses.
Boron compounds are compounds containing the element boron. In the most familiar compounds, boron has the formal oxidation state +3. These include oxides, sulfides ...
Trisodium borate is a chemical compound of sodium, boron, and oxygen, with formula Na 3 BO 3, or (Na +) 3 [BO 3] 3−. [3] It is a sodium salt of the orthoboric acid B(OH) 3.. The compound is also called trisodium orthoborate, sodium orthoborate, or just sodium borate.
