Product detail

Boron Nitride Crucible

Hot-pressed boron nitride (HBN) ceramic is an ideal material for metal smelting crucibles due to its exceptional thermal stability, chemical inertness, and non-wetting properties. It does not react with most molten metals, preventing contamination and ensuring a clean smelting process.

Mascera’s boron nitride crucibles are primarily manufactured from high-purity BN99 boron nitride ceramic, which has minimal impurities and offers superior performance in high-temperature environments. Our BN crucibles provide excellent thermal shock resistance and outstanding durability, with a maximum working temperature of 2100°C in inert gas protection and 1900°C in vacuum conditions.


Key Properties of Boron Nitride Crucibles

 ● Low thermal expansion coefficient, reducing thermal stress

 ● Excellent thermal shock resistance, ensuring durability under rapid temperature changes

 ● High working temperature capability, performing reliably in vacuum and gas protection environments

 ● Superior corrosion resistance, preventing degradation in harsh conditions

 ● Non-wetting with molten metals, eliminating contamination risks

 ● Easy machinability, allowing custom fabrication for specific applications


Applications of Boron Nitride Crucibles

Our high-purity boron nitride crucibles are widely used for sintering and smelting of various materials, including:

 ● Nonferrous and ferrous metals, such as Al, Bi, Ge, Sb, Sn, Cd, Pb, Ni, Zn, Cu, Mg, In, Fe,  ● Stainless Steel

 ● Glass melting, including soda glass, cryolite-based glass melts

 ● Molten silicon, fluoride compounds, and slag processing

Usage Tips for Boron Nitride Crucibles

To extend the lifespan and maintain the high performance of BN crucibles, follow these best practices:

 ● Always operate the boron nitride crucible under a protective gas environment (Ar or N₂) for optimal longevity.

 ● Avoid exceeding 900°C in air, as oxidation occurs beyond this temperature.

 ● Store the BN crucible in a dry, sealed container to prevent moisture absorption.

 ● Never clean the boron nitride ceramic crucible with water; use fine sandpaper or a dry cloth to remove dirt or residues.

 ● Avoid using boron nitride crucibles with Sb₂O₃, chromium oxide, molybdenum trioxide, arsenic trioxide, titanium carbide, high-lead glass glaze, boron phosphate, potassium phosphate, or chlorine compounds.
