Boron oxide - Wikipedia
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 - Wikipedia
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.
6.7: Boron Oxides, Hydroxides, and Oxyanions
Boron oxide, B 2 O 3, is made by the dehydration of boric acid, (6.7.1). It is a glassy solid with no regular structure, but can be crystallized with extreme difficulty. The structure consists of infinite chains of triangular BO 3 unit (Figure \(\PageIndex{1}\)). Boron oxide is acidic and reacts with water to reform boric acid, (6.7.1).

2020年8月14日 · Boron oxide (B 2 O 3) contains layers of trigonal planar BO 3 groups (analogous to BX 3) in which the oxygen atoms bridge two boron atoms. It dissolves many metal and nonmetal oxides, including SiO 2 , to give a wide range …
Boron monoxide - Wikipedia
Boron monoxide (BO) is a binary compound of boron and oxygen. 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. A number of allotropes of BO have been theorized ranging from molecular species, to 1D, 2D, and 3D …

Used as an insecticide; as the starting material for the synthesis of other boron compounds; as a fluxing agent in enamels and glasses; and in mixture with 2-6% boron nitride, as a bonding agent in the hot isostatic pressing of boron nitride ceramics.
Boron Oxide - an overview | ScienceDirect Topics
Boron oxide has interesting properties such as a low melting point (about 460 °C) and a low viscosity, so that it can easily fill up a matrix microcrack. 42, 96 However, this oxide will react with moisture to form boric acid (H x B y O z) according to the following equations, depending on temperature: 40, 97, 98
