Grade HBN contains a boron oxide binder; it is usable up to 550–850 °C in oxidizing atmosphere and up to 1600 °C in vacuum, but due to the boron oxide content is sensitive to water. Grade HBR uses a calcium borate binder and is usable at 1600 °C.

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 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)
Zinc borate refers to a family of inorganic compounds consisting of borate of zinc.They are white solids with the formulas 4ZnO·B 2 O 3 ·H 2 O, ZnO·B 2 O 3 ·1.12H 2 O, ZnO·B 2 O 3 ·~2H 2 O, 6ZnO·5B 2 O 3 ·3H 2 O, 2ZnO·3B 2 O 3 ·7H 2 O, 2ZnO·3B 2 O 3 ·3H 2 O, 3ZnO·5B 2 O 3 ·14H 2 O, and ZnO·5B 2 O 3 ·4.5H 2 O.
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.
Lithium borate, [1] also known as lithium tetraborate, [2] dilithium tetraborate [3] or boron lithium oxide [2] is an inorganic compound with the formula Li 2 B 4 O 7. A colorless solid, lithium borate is used in making glasses and ceramics. It is not to be confused with B 8 Li 2 O 13, also called lithium borate. [4]
