- Definition of SiC:
SiC, also known as Carborundum or Silicon Carbide (in English), is a compound of silicon and carbon. It has an atomic mass of 40.10 and a molar mass of 40.10 g/mol. The SiC molecule is made up of one silicon atom and one carbon atom. In the ionic structure of SiC, silicon and carbon form a covalent bond.
- Properties of SiC:
2.1 Physical properties of SiC:
SiC exists as a dark blue or black crystal solid at room temperature. It has no smell and its pH is not determinable as SiC is a solid.
2.2 Chemical properties of SiC:
SiC is a hard solid, with high hardness, can withstand high temperatures and has electrical conductivity.
- Common chemical equations of SiC:
SiC mainly participates in reactions with metals, acids, non-metals, and salts. However, due to its properties, specific examples of these reactions are not commonly encountered in practice.
- Synthesis of SiC:
4.1 Laboratory synthesis of SiC:
In the lab, SiC is usually synthesized through reaction between silicon and carbon.
4.2 Industrial synthesis of SiC:
In industry, SiC is produced by melting silica sand together with coal in a very hot electric furnace.
