High-Temperature Silicon Carbide Crucible & Saggar | Shijiazhuang Hongtao Technology

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 high-temperature silicon carbide (SiC) crucibles and saggers, core high-temperature containers for industrial smelting, sintering and material processing.

Our SiC crucibles and saggers are made of high-purity silicon carbide (SiC ≥98%) raw materials, produced via precision molding and high-temperature sintering[4]. They feature excellent high-temperature resistance, with long-term working temperature up to 1600℃ and short-term maximum temperature of 1650℃, maintaining stable structure in extreme heat environments[1][5].

With a bulk density of 2.75-3.16g/cm³, low apparent porosity, and superior thermal shock resistance, they resist corrosion from molten salts, acids, alkalis and molten metals[5]. Boasting zero gas release and high chemical inertness, they avoid contaminating materials, suitable for high-purity processing scenarios[1].

Widely applied in semiconductor, lithium battery, metallurgy, laboratory and new energy fields—for melting non-ferrous/precious metals, sintering battery cathode materials, crystal growth and catalyst calcination[2][4]. They support standard and customized sizes, with Shijiazhuang Hongtao committed to providing high-quality, durable SiC crucible and saggar solutions for global partners.
