This article analyzes the product characteristics and application scenarios of tantalum carbide coating and silicon carbide coating from multiple perspectives.

Hot pressing sintering is the main method for preparing high-performance SiC ceramics. The process of hot pressing sintering includes: selecting high-purity SiC powder, pressing and molding under high temperature and high pressure, and then sintering. SiC ceramics prepared by this method have the advantages of high purity and high density, and are widely used in grinding discs and heat treatment equipment for wafer processing.

Recently, the German research institute Fraunhofer IISB has made a breakthrough in the research and development of tantalum carbide coating technology, and developed a spray coating solution that is more flexible and environmentally friendly than the CVD deposition solution, and has been commercialized.

During the SiC epitaxial growth process, SiC coated graphite suspension failure may occur. This paper conducts a rigorous analysis of the failure phenomenon of SiC coated graphite suspension, which mainly includes two factors: SiC epitaxial gas failure and SiC coating failure.

The article explains the temperature gradient in a single-crystal furnace. It covers the static and dynamic heat fields during crystal growth, the solid-liquid interface, and the temperature gradient's role in solidification.

From the application perspective of SiC single crystal growth, this article compares the basic physical parameters of TaC coating and SIC coating, and explains the basic advantages of TaC coating over SiC coating in terms of high temperature resistance, strong chemical stability, reduced impurities, and lower costs.
