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.
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)
Often the boron in borides has fractional oxidation states, such as −1/3 in calcium hexaboride (CaB 6). From the structural perspective, the most distinctive chemical compounds of boron are the hydrides. Included in this series are the cluster compounds dodecaborate (B 12 H 2− 12), decaborane (B 10 H 14), and the carboranes such as C 2 B 10 ...
[88] [89] The major global industrial-scale use of boron compounds (about 46% of end-use) is in production of glass fiber for boron-containing insulating and structural fiberglasses, especially in Asia. Boron is added to the glass as borax pentahydrate or boron oxide, to influence the strength or fluxing qualities of the glass fibers. [90]
Boron monoxide (BO) is a binary compound of boron and oxygen. It has a molar mass of 26.81 g/mol. It has a molar mass of 26.81 g/mol. The material was first reported in 1940, [ 1 ] with a modified synthetic procedure published in 1955, [ 2 ] however, the material's structure had remained unknown for nearly a century.
An oxide (/ ˈ ɒ k s aɪ d /) is a chemical compound containing at least one oxygen atom and one other element [1] in its chemical formula. "Oxide" itself is the dianion (anion bearing a net charge of –2) of oxygen, an O 2– ion with oxygen in the oxidation state of −2. Most of the Earth's crust consists of oxides. Even materials ...
The amount of boric oxide affects the glass properties in a particular way. Apart from the highly resistant varieties (B 2 O 3 up to a maximum of 13%), there are others that – due to the different way in which the boric oxide is incorporated into the structural network – have only low chemical resistance (B 2 O 3 content over 15%).

Atomic structure and electron micrographs of ideal (top) and twinned (bottom) B 6 O. Green spheres are boron, red spheres are oxygen. [8]B 6 O has a strong covalent nature and is easy to compose at temperatures greater than 1,973 K. [7] Boron suboxide has also been reported to exhibit a wide range of superior properties such as high hardness with low density, high mechanical strength ...
