Fused Silica Quartz Plate – Heat Resistant

Our high-purity quartz plates are precision-crafted from 99.99% fused silica, engineered for exceptional thermal stability, chemical inertness, and optical clarity. Available in customizable sizes (thickness 0.5–50mm, length/width up to 1200×2400mm), these plates boast a low thermal expansion coefficient, resisting rapid temperature swings from -20°C to 1200°C without cracking. Featuring a polished, scratch-resistant surface with ≥92% UV-visible light transmittance, they excel in harsh industrial environments, unaffected by most acids (except hydrofluoric acid) and alkaline solutions. Ideal for semiconductor wafer carriers, laboratory instrument panels, solar panel substrates, and high-temperature furnace windows, our quartz plates deliver reliable performance in precision manufacturing, scientific research, and optoelectronics applications. We offer OEM services, including edge grinding, drilling, and coating, to meet bespoke client requirements. Strict quality control ensures consistent thickness and flatness, making our quartz plates a trusted choice for global industrial and research partners.
