  • Different types of SiC ceramics

    Silicon carbide (SiC) ceramic is a type of advanced ceramic material known for its exceptional properties and wide range of applications. It is composed of silicon (Si) and carbon (C) atoms arranged in a crystal lattice structure, resulting in a hard and strong material with excellent thermal and electrical conductivity.

  • About defects in SiC crystals - Micropipe

    SiC substrate can have microscopic defects, such as Threading Screw Dislocation (TSD), Threading Edge Dislocation (TED), Base Plane Dislocation (BPD), and others. These defects are caused by deviations in the arrangement of atoms at the atomic level. SiC crystals may also have macroscopic dislocations, like Si or C inclusions, micropipe, hexagonal voids, polymorphs, etc. These dislocations are typically large in size.

  • Dislocation in SiC crystals

    SiC substrate can have microscopic defects, such as Threading Screw Dislocation (TSD), Threading Edge Dislocation (TED), Base Plane Dislocation (BPD), and others. These defects are caused by deviations in the arrangement of atoms at the atomic level.

  • SiC Epitaxy

    There are two types of epitaxy: homogeneous and heterogeneous. In order to produce SiC devices with specific resistance and other parameters for different applications, the substrate must meet the conditions of epitaxy before production can begin. The quality of the epitaxy affects the device's performance.

  • 3 methods of graphite molding

    The four main molding methods for graphite molding are: extrusion molding, molding, vibratory molding and isostatic molding. Most of the common carbon/graphite materials on the market are molded by hot extrusion and molding (cold or hot), and isostatic molding is a method with leading molding performance. Vibration molding is generally used to manufacture medium and coarse structural graphite, particle size between 0.5-2mm particle size, generally dominated by di-roasted graphitized products, density between 1.55-1.75kg/m³, coarser particles, rougher surface, can not be used for precision machining. It is mainly used in chemical industry and metal smelting.

  • Silicon Carbide Wafer Epitaxy Technology

    Silicon Carbide generally uses the PVT method, with a temperature of more than 2000 degrees, a long processing cycle, and low output, so the cost of Silicon Carbide substrates is very high.
