The 12 inch quartz polished plates are precision-manufactured components used in semiconductor and photovoltaic manufacturing processes requiring ultra-clean, smooth surfaces. Made from high-purity fused quartz, these plates undergo advanced polishing techniques to achieve superior surface flatness and optical clarity.

Their exceptional chemical inertness and thermal stability make them ideal for use in high-temperature environments, such as in diffusion, oxidation, and CVD reactors. The polished surface minimizes particle adhesion and contamination, supporting high yield and process consistency.
