Boron Nitride Crucible

Boron Nitride crucibles are high-temperature containers made from Boron Nitride ceramic material. They are used for melting, casting, and processing various metals and alloys, as well as for high-temperature chemical reactions. Boron Nitride crucibles are known for their excellent thermal shock resistance, high temperature stability, and low wettability by many molten metals and alloys.

Product Description

Features & Benefits

  • High-temperature stability: Boron Nitride crucibles can withstand temperatures up to 1800°C in an oxidizing atmosphere and up to 2800°C in an inert atmosphere.
  • Excellent thermal shock resistance: Boron Nitride crucibles can withstand rapid temperature changes without cracking or breaking.
  • Low wettability: Boron Nitride crucibles are resistant to wetting by many molten metals and alloys, which reduces the risk of contamination and improves the quality of the final product.
  • Chemical inertness: Boron Nitride crucibles are highly resistant to most chemicals, acids, and bases, making them suitable for a wide range of applications.
  • Non-wetting surface: Boron Nitride crucibles have a non-wetting surface, which means that molten materials are less likely to adhere to the surface and are easy to remove.
  • High purity: Boron Nitride crucibles are available in high-purity grades, which makes them suitable for use in demanding applications such as semiconductor manufacturing.

Markets & Applications

  • Melting and casting of metals and alloys: Boron Nitride crucibles are used in the production of various metals and alloys, including gold, silver, platinum, and copper.
  • Chemical reactions: Boron Nitride crucibles are used in high-temperature chemical reactions such as combustion, pyrolysis, and calcination.
  • Semiconductor manufacturing: Boron Nitride crucibles are used in the production of semiconductors and other electronic components.
  • Powder metallurgy: Boron Nitride crucibles are used in the production of metal powders by gas atomization.
  • Glass melting: Boron Nitride crucibles are used in the production of specialty glasses and optical fibers.
