The quartz boat is a specialized glass vessel manufactured through vacuum melting and precision processing of high-purity silicon dioxide (SiO₂≥99.999%). With a softening point of 1730°C, long-term operational tolerance of 1100°C, and thermal stability of ±0.02mm/1000°C, it is engineered for extreme high-temperature environments such as semiconductor diffusion furnaces and photovoltaic coating equipment. Key advantages include:
① Exceptional Chemical Inertness: Resistant to strong acids (except HF) and molten alkalis, with acid resistance 30× that of ceramics and 150× stainless steel.
② Full-Spectrum Optical Clarity: >93% transmittance from UV to IR, ideal for laser cavities and optical sensors.
③ Superior Electrical Insulation: Resistivity up to 1×10¹⁸ Ω·cm, suitable for high-voltage applications.
Available in diameters ranging from 1.5 meters to 1mm, the product supports deep customization including non-standard grooves, gradient doping (e.g., radiation-resistant yttrium doping, ultra-thin walls of 0.1mm), and is widely used in semiconductor wafer growth, PV silicon diffusion, high-temperature lab reactions, and spacecraft thermal management systems.

1. Q: Why is it called quartz?
A: It's called quartz because the material is derived from crystalline silicon dioxide (SiO₂), sharing the same chemical composition as natural quartz minerals.
2. Q: Why is quartz better?
A: Quartz is better due to its superior thermal stability (up to 1100°C), optical clarity (UV-IR transmission), and chemical resistance compared to conventional glass or ceramics.
