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.

Graphitising is the process of transforming non-graphitic charcoal into graphitic charcoal with graphite three-dimensional regular ordered structure by high-temperature heat treatment, making full use of electrical resistance heat to heat the charcoal material to 2300~3000 ℃, and transforming the charcoal with amorphous chaotic layer structure into ordered graphite crystalline structure.

Single crystal silicon and polycrystalline silicon each have their own unique advantages and applicable scenarios. Single crystal silicon is suitable for high-performance electronic products and microelectronics due to its excellent electrical and mechanical properties. Polycrystalline silicon, on the other hand, dominates the field of solar cells due to its low cost and good photoelectric conversion efficiency.

Silicon is the second most abundant element on Earth after oxygen. Most silicon is found in soil, rocks, natural water, trees, and plants.
