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℃ 95/99 alumina high-temperature refractory plates, core products for high-temperature industrial applications.

Available in 95% and 99% alumina purity options, these refractory plates feature excellent high-temperature resistance, with a maximum working temperature of 1800℃ and stable performance under long-term high-temperature conditions. Made of high-purity α-Al₂O₃ powder via isostatic pressing and high-temperature sintering, they have a density of 3.6-3.98g/cm³ and low porosity (<0.1%).

The plates boast superior chemical inertness, corrosion resistance to acids, alkalis and molten salts, as well as excellent wear resistance and thermal shock resistance. With precise dimensional control (tolerance ±0.05mm) and smooth surface (roughness ≤0.4μm), they are easy to install and use in various high-temperature equipment.

Widely applied in industrial kilns, aerospace, new energy and material processing fields, they serve as furnace liners, support plates and thermal insulation components. Shijiazhuang Hongtao provides customized size and thickness solutions, adhering to innovation to deliver high-quality alumina refractory products for global partners.
