In semiconductor manufacturing, Chemical Mechanical Planarization (CMP) plays a vital role. The CMP process combines chemical and mechanical actions to smooth the surface of silicon wafers, providing a uniform foundation for subsequent steps such as thin-film deposition and etching. CMP polishing slurry, as the core component of this process, significantly impacts polishing efficiency, surface quality, and the final performance of the product

In the process of growing silicon carbide (SiC) crystals via the Physical Vapor Transport (PVT) method, the extreme high temperature of 2000–2500 °C is a “double-edged sword” — while it drives the sublimation and transport of source materials, it also dramatically intensifies impurity release from all materials within the thermal field system, especially trace metallic elements contained in conventional graphite hot-zone components. Once these impurities enter the growth interface, they will directly damage the core quality of the crystal. This is the fundamental reason why tantalum carbide (TaC) coatings have become a “mandatory option” rather than an “optional choice” for PVT crystal growth.

Silicon carbide abrasives are typically produced using quartz and petroleum coke as primary raw materials. In the preparatory stage, these materials undergo mechanical processing to achieve the desired particle size before being chemically proportioned into furnace charge.
