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 clay graphite crucibles, core containers for high-temperature smelting and laboratory use.

Our high-temperature clay graphite crucible is made of high-quality refractory clay and 15-25% high-purity graphite, produced via scientific proportioning and high-temperature firing. 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.

It has outstanding thermal conductivity and thermal shock resistance, avoiding cracking under rapid cooling and heating cycles. With good chemical inertness, it resists corrosion from acidic, alkaline slags and molten metals, ensuring no contamination to smelted materials.

Widely applied in metallurgy, jewelry making, laboratory research and metal recycling industries—for melting non-ferrous metals, precious metal purification and alloy preparation. It supports standard and customized sizes, with Shijiazhuang Hongtao committed to providing high-quality, reliable clay graphite crucible solutions for global partners.
