The nine-hole crucible is a high-end refractory container specifically designed for multi-station batch production. Made from high-purity graphite and alumina composite materials through molding and high-temperature sintering, its multi-hole partitioned structure and superior material properties make it a core component for mass production in the electronics, metallurgy, and new materials fields.
The product features a one-piece molded design with nine evenly distributed independent holes (hole diameter 10-50mm optional), a hole wall thickness of ≥8mm, and an overall dimensional tolerance of ≤±0.3mm, ensuring a uniform heating deviation of ≤5℃ across all stations. It boasts excellent high-temperature resistance, with a long-term operating temperature of 1800-2200℃, and remains free from deformation or cracking at high temperatures. Its thermal conductivity is ≥120W/(m·K), resulting in a 30% improvement in heating and cooling rates.
With low impurity content (ash content ≤0.05%), corrosion resistance, and high wear resistance, it can withstand long-term corrosion from molten metals and chemical raw materials, extending its service life by 1.5 times compared to ordinary multi-hole crucibles. Excellent sealing performance reduces raw material volatilization loss by ≥15%, and it can process nine sets of workpieces simultaneously, increasing production efficiency by 200%.
Available in standard volumes of 5-30L, with customizable hole sizes and overall specifications, it is widely used in applications such as lithium battery anode material sintering, precious metal smelting, and electronic component heat treatment. Compatible with tunnel kilns, well furnaces, and other equipment, it is supplied directly from the factory, offering technical support and after-sales service. It is a core industrial tool that combines efficient mass production with stable quality.
