Boron nitride crucible

Boron nitride crucible introduction

Boron nitride ceramic is an advanced material with a wide range of exceptional properties, making it a versatile and highly sought-after material in various industries. Engineered from boron and nitrogen atoms, this ceramic material exhibits remarkable thermal stability, outstanding electrical insulation, high thermal conductivity, and excellent chemical inertness. With high thermal conductivity, hBN ceramic efficiently dissipates heat. As hBN has very low thermal expansion coefficient, it has great thermal shock resitant. And, with great chemical inertness, making it an ideal material for crucible to process molten material.

QS Advanced Materials Inc has developed different grades of boron nitride ceramics to fulfill customer’s various requirements. The most regular material is BN99, pure boron nitride with little CaO as binder. We also have high purity TPBN (equivalent to grade HBT) for applications that requires high purity material. TPBN have BN content >99.9%, one step behind 99.99% PBN.

Boron nitride ceramic finds application as components in high-temperature furnaces, thermal management systems, electrical insulators, protective coatings, and even in advanced electronic devices. Its unique combination of properties makes it invaluable for demanding applications where performance, durability, and reliability are essential factors. Its excellent electrical insulation makes it valuable in electrical and electronic applications that require isolation such as PVD equipment. Furthermore, hBN ceramics low coefficient of friction provides lubrication and wear resistance, particularly in high-temperature environments.
