Product detail
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.
