Silicon carbide (SiC), also known as carborundum (/ ˌ k ɑːr b ə ˈ r ʌ n d əm /), is a hard chemical compound containing silicon and carbon. A wide bandgap semiconductor, it occurs in nature as the extremely rare mineral moissanite, but has been mass-produced as a powder and crystal since 1893 for use as an abrasive.

2025年1月1日 · This paper reviews the research progress of SiC, including the crystal structure of SiC, the growth method of SiC crystals, the unique properties, and the preparation of SiC materials from silicon cutting waste.

Moissanite (/ ˈ m ɔɪ s ə ˌ n aɪ t /) [5] is naturally occurring silicon carbide and its various crystalline polymorphs.It has the chemical formula SiC and is a rare mineral, discovered by the French chemist Henri Moissan in 1893. Silicon carbide or moissanite is useful for commercial and industrial applications due to its hardness, optical properties and thermal conductivity.

2023年11月30日 · Silicon carbide crystallizes in a densely packed structure that is covalently bound to each other. The Si and C atoms in a SiC crystal generate highly strong tetrahedral covalent connections (bond energy=4.6 eV) by exchanging electron pairs in sp3 hybrid orbitals.
