China TaC coated guide ring Manufacturer, Supplier, Factory

With the development of the solar photovoltaic industry, diffusion furnaces and LPCVD furnaces are the main equipment for the production of solar cells, which directly affect the efficient performance of solar cells. Based on the comprehensive product performance and usage cost, silicon carbide ceramic materials have more advantages in the field of solar cells than quartz materials. The application of silicon carbide ceramic materials in the photovoltaic industry can greatly help photovoltaic enterprises reduce auxiliary material investment costs, improve product quality and competitiveness. The future trend of silicon carbide ceramic materials in the photovoltaic field is mainly towards higher purity, stronger load-bearing capacity, higher loading capacity, and lower cost.

This blog takes "What is SiC-coated graphite susceptor?" as its theme, and discusses it from the perspectives of Epitaxial layer and its equipment, Importance of SiC coated graphite susceptor in CVD equipment, SiC Coating technology, Market competition and Vetek Semiconductor’s technological innovation.

Tantalum carbide (TaC) coating can significantly extend the life of graphite parts by improving high temperature resistance, corrosion resistance, mechanical properties and thermal management capabilities. Its high purity characteristics reduce impurity contamination, improve crystal growth quality, and enhance energy efficiency. It is suitable for semiconductor manufacturing and crystal growth applications in high-temperature, highly corrosive environments.

In the preparation of high-quality and high-yield silicon carbide substrates, the core requires precise control of production temperature by good thermal field materials. Currently, the thermal field crucible kits mainly used are high-purity graphite structural components, whose functions are to heat molten carbon powder and silicon powder as well as to maintain heat.

As the 8-inch silicon carbide (SiC) process matures, manufacturers are accelerating the shift from 6-inch to 8-inch. Recently, ON Semiconductor and Resonac announced updates on 8-inch SiC production.

On September 5, 2025, a customer from Poland visited a factory under VETEK to learn about our advanced technologies and innovative processes in the production of carbon fiber products.
