The liquid phase method is closer to the thermodynamic equilibrium conditions and is able to grow SiC crystals with better quality.

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.

Crystal growth is the core link in the production of Silicon Carbide substrates, and the core equipment is the crystal growth furnace. Similar to traditional crystalline silicon-grade crystal growth furnaces, the furnace structure is not very complex and mainly consists of a furnace body, a heating system, a coil transmission mechanism, a vacuum acquisition and measurement system, a gas path system, a cooling system, a control system, etc., among which Thermal field and process conditions determine the quality, size, conductive properties and other key indicators of Silicon Carbide crystals.

Thick, high-purity silicon carbide (SiC) layers, typically exceeding 1mm, are critical components in various high-value applications, including semiconductor fabrication and aerospace technologies. This article delves into the Chemical Vapor Deposition (CVD) process for producing such layers, highlighting key process parameters, material characteristics, and emerging applications.

Isostatic pressing technology is a critical process in the manufacturing of isostatic graphite, largely determining the performance of the final product. As such, comprehensive research and optimization of isostatic graphite production remain essential focal points in the industry.

Plasma is the fourth state of matter, and it plays a crucial role in both industrial applications and natural phenomena.
