Semicorex's SiC crystal growth furnace component, the porous graphite barrel, will bring three major benefits and can effectively strengthen the competitiveness of domestic SiC substrates:

Tantalum carbide coating is an important high-strength, corrosion-resistant and chemically stable high-temperature structural material with a melting point of up to 4273 °C, one of the several compounds with the highest temperature resistance. It has excellent high-temperature mechanical properties, resistance to high-speed airflow scouring, ablation resistance, and good chemical and mechanical compatibility with graphite and carbon/carbon composites. Therefore, in the epitaxial process of GaN LEDs and SiC power devices such as MOCVD, TaC coating has excellent acid and alkali resistance to H2, HCl, NH3, which can completely protect the graphite substrate material and purify the growth environment.

The ultra-high synthesis temperature and the difficulty of achieving dense sintering of SiC ceramics have limited their development. The sintering process is crucial for SiC ceramics.

Silicon carbide (SiC) is a wide-bandgap semiconductor material that has garnered significant attention in recent years due to its exceptional performance in high-voltage and high-temperature applications. This study systematically explores the various characteristics of SiC crystals grown using modified process conditions.

At first glance, quartz (SiO2) material looks very similar to glass, but what is special is that ordinary glass is composed of many components (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.), while quartz only contains SiO2, and its microstructure is a simple network composed of silicon dioxide tetrahedral structural units.
