PRODUCT INTRODUCTION

Hot Pressed Boron Nitride is an excellent electrical insulator and does not require humidity to act as a lubricant. BN has poor mechanical properties, however, it generally has very high temperature heat capacity, excellent thermal conductivity, outstanding dielectric strength and easy machinability. In reducing and inert atmospheres, BN can withstand temperatures in excess of 2000℃. BN comes in a variety of different grades in solid and powder form, all with slightly differing properties.

APPLICATIONS

Thermal Management
Excellent electrical insulation and thermal conductivity make BN very useful as a heat sink in high-power electronic applications. Its properties compare favorably with beryllium oxide, aluminum oxide, and other electronic packaging materials, and are easier machinable to desired shapes and sizes.

High Temperature Environments
Temperature stability and excellent resistance to thermal shock make BN the ideal material in the toughest high-temperature environments such as equipment for plasma arc welding, diffusion source wafers, and semiconductor crystal growth equipment & processing.

Molten Metal Handling
BN is inorganic, inert, nonreactive with halide salts and reagents, and is not wet by most molten metals and slags. These characteristics, combined with low thermal expansion, make it ideal for interface materials used in various molten metal processes.
