Shijiazhuang Hongtao Technology Co., Ltd., a professional high-tech enterprise based in Zhengding County, Shijiazhuang, Hebei, China, specializes in R&D, manufacturing and customization of 1800℃ alumina crucibles, core high-temperature containers for industrial production and laboratory use.

Our 1800℃ alumina crucible is made of high-purity α-alumina (Al₂O₃ ≥ 99%), produced via high-temperature sintering and precision molding. It features excellent high-temperature resistance, with long-term working temperature up to 1600℃ and short-term maximum temperature of 1800℃, ensuring stable performance in extreme heat environments.

With a density of 3.8-3.95g/cm³, it has strong mechanical strength, good thermal shock resistance and chemical inertness, resisting most acids, alkalis and molten salts without contaminating samples. It is airtight, non-porous and easy to clean, suitable for high-purity scenarios.

Widely applied in metallurgy, laboratory analysis, new energy and electronic industries—for metal smelting, sample ashing, high-temperature sintering and crystal growth. It supports standard sizes (5mL-5000mL) and customized dimensions, with Shijiazhuang Hongtao committed to providing high-quality, reliable alumina crucible solutions for global partners.
