Product details

High purity boron nitride (BN) crucibles are made of >99.6% purity boron nitride. Each BN crucible includes a crucible and a lid

Boron Nitride is a synthetic technical ceramic material. It has outstanding thermal characteristics: high thermal conductivity (751 W/mK) and excellent thermal shock resistance. It is stable up to 2000 °C in reducing atmospheres, and up to 900 °C in oxidizing atmospheres. The unique property of BN crucible is that it is non-wetting with molten metal. It is widely used for crystal growth, melting metals, rare earth materials, fluorides, glass, silicon, molten salt and luminescent materials. It is ideal for oxygen sensitive applications.

MSE Supplies offers a wide range of sizes of boron nitride (BN) crucibles for laboratory uses. If you need custom made BN crucibles, please contact us for a quote.
