Salt-like materials
Salt-like carbides are composed of highly electropositive elements such as the the alkali metals, alkaline earths, and group 3 metals including (scandium, yttrium and lanthanum.
The naming of ionic carbides is not consistent and can be quite confusing.
Acetylides
The hypothetical polyatomic ion C22
Methanides
The monatomic ion C4
Examples of compounds that are described as methanides include C4
Sesquicarbides
The polyatomic ion C34
Covalent carbides
The carbides of silicon and boron are described as "covalent carbides", although virtually all compounds of carbon exhibit some covalent character. Silicon carbide has two similar crystalline forms, which are both related to the diamond structure. Boron carbide, B4C, on the other hand has an unusual structure which includes icosahedral boron units linked by carbon atoms. In this respect boron carbide is similar to the boron rich borides. Both silicon carbide, SiC, (carborundum) and boron carbide, B4C are very hard materials and refractory. Both materials are important industrially. Boron also forms other covalent carbides, e.g. B25C.
