Since there is very little silicon metal naturally formed, the vast majority of silicon metal in life is artificially processed. Metal silicon has strong hardness and can be used as an important abrasive. But different from other ordinary abrasive metal silicon, it has many properties and can be used in various fields. It has high temperature resistance, thermal conductivity, electrical conductivity and so on. The following is an introduction to the properties and basic structure of metal silicon.
Metal silicon's high temperature resistance and thermal conductivity make it one of the preferred kiln furniture materials for tunnel kilns or shuttle kilns, and its electrical conductivity makes it an important electric heating element. Silicon metal is a typical covalently bonded stable compound. Theoretically speaking, metal silicon is formed by stacking SiC tetrahedrons, and the only difference is parallel or antiparallel combination. There are 75 variants of SiC, all of which structures can be divided into cubic, hexagonal and rhombohedral. α-SiC is stable at high temperature, and β-SiC is stable at low temperature. β-SiC can be transformed into α-SiC at 2100-2400°C, and β-SiC can be made from a simple mixture of silicon and carbon at a temperature of about 1450°C. SiC microstructures can be analyzed and quantitatively determined using transmission electron microscopy and X-ray diffraction detection techniques. In order to distinguish various structures, corresponding naming methods are needed. The commonly used naming method is: the low-temperature type of cubic metal silicon is called β-SiC, and the other hexagonal and rhombic unit cell structures are all called α-SiC. This method of nomenclature does not conform to the conventions of phase law and mineralogical nomenclature, but it is quite popular because of its convenience.
