Silicon Carbide: An In - Depth Look at Its Features and Benefits
Silicon carbide has a complex and stable internal structure. The silicon-carbon tetrahedron, as the basic building block, forms a three-dimensional network structure through covalent bonds. This structure not only determines its high hardness and wear resistance but also affects its electrical and thermal properties. For example, the strong covalent bonds make it difficult for electrons to move freely, resulting in its semiconductor properties. The arrangement of atoms in the crystal also affects its thermal conductivity. The regular arrangement of atoms in the crystal structure of SiC enables efficient heat transfer, endowing it with a relatively high thermal conductivity.
In terms of preparation, the traditional carbon reduction of silica method is still widely used in large-scale industrial production due to its relatively simple process and low cost. However, in order to meet the increasing demand for high-purity and high-quality SiC in some high-tech fields, new preparation technologies are being continuously explored. For example, the physical vapor transport (PVT) method can grow high-quality single-crystal SiC. In this method, SiC source materials are vaporized at high temperatures and then deposited on a seed crystal to grow a single crystal. This method can effectively control the growth rate and quality of the crystal, obtaining SiC single crystals with fewer defects, which are very important for applications in the semiconductor field.
