The Critical Role of Quartz Boats in Wafer ProcessingA quartz boat — also referred to as a wafer carrier or diffusion boat — is a precision-machined holder fabricated from high-purity fused silica (SiO₂) that securely positions silicon wafers during high-temperature thermal processing steps. These components are indispensable in horizontal an

Quartz rod is a high-performance cylindrical product made of fused silica (SiO₂ ≥ 99.99%). It features exceptional high-temperature resistance (softening point ~1730°C, long-term use at 1100°C), excellent UV-IR transmittance, low thermal expansion, and superb chemical inertness (resistant to most acids except HF). It also offers outstanding e
