The upstream of precision optics primarily involves the manufacturing of optical raw materials, with the main participants being material enterprises that produce optical glass
The silicon carbide wafer grinding and polishing industry is currently at a pivotal stage of rapid development in the third-generation semiconductor industry. Due to the extremely high hardness of silicon carbide materials and the significant processing challenges they pose, the precision and stability of grinding and polishing processes are subject to stringent requirements.
As an important branch of functional ceramics, precision ceramics are widely used in high-end fields such as electronics, electrical engineering, machinery manufacturing, medical devices, and aerospace due to their excellent mechanical strength, high wear resistance, superior thermal stability, and outstanding chemical inertness.
