High-Temperature Quartz Crucible | Shijiazhuang Hongtao Technology

Our high-temperature quartz crucible is made of 99.99% high-purity fused silica (SiO₂), produced via precision melting and shaping technology, ensuring excellent high-temperature resistance. Its long-term working temperature reaches 1200℃, with short-term maximum temperature up to 1600℃, maintaining stable performance in extreme heat environments.

Widely applied in semiconductor, photovoltaic, metallurgical and laboratory fields—for crystal growth, metal melting and high-purity material processing. It is also ideal for annealing of electronic components, sintering of ceramic substrates, calcination of catalyst materials, and heat treatment of small precision parts. Additionally, it is widely used in new energy battery material processing, optical glass manufacturing, and rare earth material purification. Supporting standard and customized sizes, Shijiazhuang Hongtao is committed to providing high-quality, reliable quartz sagger boat solutions for global partners.
