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.
Guitar slide made of borosilicate glass. Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass.

Boron oxide may refer to one of several oxides of boron: Boron trioxide (B 2 O 3, diboron trioxide), the most common form;
The mean oxidation number for the boron atoms is then simply the ratio of hydrogen to boron in the molecule. For example, in diborane B 2 H 6, the boron oxidation state is +3, but in decaborane B 10 H 14, it is 7 / 5 or +1.4. In these compounds the oxidation state of boron is often not a whole number.
Trioxidane (systematically named dihydrogen trioxide, [2] [3]), also called hydrogen trioxide [4] [5] is an inorganic compound with the chemical formula H[O] 3 H (can be written as [H(μ-O 3)H] or [H 2 O 3]). It is one of the unstable hydrogen polyoxides. [4] In aqueous solutions, trioxidane decomposes to form water and singlet oxygen:

These reactions can also be initiated photochemically by UV radiation in the compounds absorption range at about 230 nm. [3] [4] [5] B(N 3) 3 → BN 3 + 3 N 2 B(N 3) 3 → BN + 4 N 2. In contact with water, it undergoes hydrolysis to hydrazoic acid and boron trioxide. [3] 2 B(N 3) 3 + 3 H 2 O → 6 HN 3 + B 2 O 3
