Aluminum Nitride Ceramic Crucibles

Aluminum nitride materials are diamond-like covalent nitrides with a hexagonal wurtzite crystal structure. Featuring exceptional thermal and mechanical properties, aluminum nitride materials are ideal alternatives to conventional graphite materials for crucible manufacturing. Semicorex enforces rigorous quality control commencing with raw material screening and uses high-purity aluminum nitride materials to produce our crucibles, making them exhibit multiple excellent performance listed below:

1. Ultra-high high-temperature resistance

Semicorex aluminum nitride ceramic crucibles are able to retain consistent mechanical performance even at temperatures up to 1500°C, making them well-suited for the extreme high-temperature operating environments.

2. High thermal conductivity

With excellent thermal conductivity, Semicorex aluminum nitride ceramic crucibles achieve rapid heat transfer, which facilitates of the formation of a favorable temperature gradients for melting, thus greatly improving the process results.

3. Strong chemical corrosion resistance

Semicorex aluminum nitride ceramic crucibles deliver favorable wettability and erosion resistance against molten metal and perform well when contacting corrosive molten salts like carbonates, chlorides and cryolite, because of their reliable chemical stability.

4. Low contamination

Semicorex aluminum nitride ceramic crucibles are manufactured with a high-purity composition, and will not react with molten materials, which drastically lowers the contamination risk to molten materials.

Applications of Semicorex aluminum nitride ceramic crucibles

Benefiting from superior properties outlined above, Semicorex aluminum nitride ceramic crucibles serve as the dependable containers for high-temperature melting, which are widely applied in the following fields.
