Boride - Wikipedia
网页A boride is a compound between boron and a less electronegative element, for example silicon boride (SiB 3 and SiB 6). The borides are a very large group of compounds that are generally high melting and are covalent more than ionic in nature. Some borides exhibit very useful physical properties.
6.3: Borides - Chemistry LibreTexts
网页Table 6.3.1: The melting points of Group 4 metals and their borides. The structures of metal borides depends on the M:B ratio. Borides with an isolated boron atom have a low B:M ratio: M 4 B, M 3 B, M 2 B, M 5 B 2, and M 7 B 3. In such compounds the boron atom is normally in a triangular-prismatic or square-antiprismatic hole in a metal lattice.

Boride - an overview | ScienceDirect Topics
网页Boron is a nonmetal and belongs to group 13 of the elements. It reacts with the less electronegative elements, mostly metals (e.g., Hf, Mg, Al, W, Ta, and La) to form borides. Borides are hard, and they have good conductivity along with high melting temperatures.
Harnessing the Potential of Boride: in Modern Industries
网页2024年7月25日 · Borides are a group of binary compounds consisting of boron and a less electronegative element, often a metal. These compounds are known for their exceptional hardness, high melting points, and excellent thermal and electrical conductivity.
13.10: Metal Borides - Chemistry LibreTexts
网页2023年1月16日 · Expand/collapse global location. 13.10: Metal Borides. Page ID. In metal borides, the bonding of boron varies depending on the atomic ratio B/M. Diborides have B/M = 2, as in the well-known superconductor MgB 2; they crystallize in a hexagonal AlB 2 -type layered structure. Hexaborides have B/M = 6 and form a three-dimensional boron framework ...
