✅ Typical Applications of Boron Nitride Crucibles（BN）

• Electrical insulators in high-temperature vacuum environments
• Boron nitride insulators used in high-temperature furnaces
• Spacer material in the glass melting industry
• BN components used in ion implantation equipment

✅ Here Are Some Tips for Using Boron Nitride Crucibles

• It is recommended to use the crucibles in a protective atmosphere, such as argon or nitrogen.
• Use in open air is not recommended.
• Boron nitride ceramics are prone to moisture absorption and should be stored in sealed containers to prevent humidity damage.
• Do not rinse with water. Use fine sandpaper to gently remove any residue for cleaning purposes.

✅ What Materials Can Be Used with Boron Nitride Crucibles?

Boron nitride crucibles are suitable for the melting and processing of a variety of non-ferrous metals, including zinc, iron, magnesium, copper, nickel, aluminum, and bismuth. They are also compatible with certain high-performance alloys such as Co-Zr-Nb and Fe-Co-Ni-Si.
At room temperature, the crucibles exhibit excellent corrosion resistance as they do not react with water or acids. Additionally, they show good chemical compatibility with materials such as boric acid, ammonia, and rare earth elements.

⚠️ Material Limitations When Using BN Crucibles

Avoid using BN crucibles with materials such as titanium carbide, molybdenum trioxide, antimony trioxide, arsenic trioxide, and chromium trioxide.
BN crucibles may also be corroded by boron phosphate at temperatures above 1400°C in a nitrogen atmosphere, and they will react with chlorine gas and concentrated alkalis at elevated temperatures.
