Product detail

Boron Nitride Crucible

Hot pressed boron nitride (HBN) ceramic is an ideal ceramic material for metal smelting crucibles because it will not react with most molten metals and has good non-wetting properties, ensuring that the molten metals will not be polluted. Boron nitride crucibles of Mascera are mostly produced in high purity boron nitride ceramic (BN99 type), which has the lowest impurities. Our boron nitride crucibles have excellent temperature resistance and thermal shock resistance, the maximum working temperature is up to 2100 ℃ in inert gas protection and 1900℃ in vaccum conditions.

Main properties of boron nitride crucibles

Tips for Using Boron Nitride Crucibles

To maximize the life span of boron nitride crucible, operation under protective gas (Ar or N2) environment is strongly recommended. 

Working temperature in the air should not exceed 900℃, oxidation will occur when more than 900°C.

The crucible shall be stored in the dry environment inside a sealed container.

Never wash the crucible with water. Use fine sandpaper or cloth to remove any dirts or residues.

Not suitable for the use with Sb2O3, chromium oxide, molybdenum trioxide, arsenic trioxide, titanium carbide, high lead glass glaze, boron phosphate, potassium phosphate, chlorine.
