Does the company’s self-developed silicon carbide crystal growth equipment and graphite materials sell to other companies?

Tianyue Advanced: Dear investors, hello! Since its establishment, the company has focused on the preparation technology of silicon carbide substrates, achieved fully independent diameter expansion from 2 inches to 8 inches, and mastered the core technology of the entire process of substrate preparation covering equipment design, thermal field design, powder synthesis, crystal growth, substrate processing, etc. At the same time, the company attaches importance to the reserve of forward-looking technologies. At present, the company has formed large-scale production and sales of 6-inch conductive silicon carbide substrates, 6-inch semi-insulating silicon carbide substrates, 4-inch semi-insulating silicon carbide substrates and other products. Up to now, the company's self-developed silicon carbide crystal growth equipment and graphite materials have not been directly sold to the outside world, and are mainly used by the company to prepare silicon carbide semiconductor materials. Thank you for your attention!
