BORON NITRIDE INSULATORS/WASHERS FOR VACUUM FURNACES IN ALANDUR

Momentive offers Boron Nitride Insulators and washers for Vacuum Furnaces. Hot-pressed BN is compacted at temperatures up to 2000 C and pressures up to 2000 psi to form a dense, strong engineering material that is easily machined. It is available in standard and custom shapes and has several unique properties which make it valuable in a wide range of challenging industrial applications. Four Material Grades Grades HBC and HBT are our highest purity hot-pressed boron nitrides. They are diffusion bonded and feature a low dielectric constant, minimal moisture pick-up and low loss tangent making them ideal for electronic applications. Grade HBT, although lower in strength and density than HBC, is available at lower cost and shorter lead times. Grade HBN uses small amounts of boric oxide as a binder; it is used in applications where hydration and thermal shock are not a concern. Grade HBR uses calcium borate as a strengthening binder and is moisture insensitive. For applications demanding even higher strength and durability, Momentive offers grade BIN77 composite material; see publication 81520 for more details. Thermal Management of Electronic Devices The unique combination of electrical resistivity and thermal conductivity makes BN an ideal heat sink in high power electronic applications. Its properties compare favorably with beryllium oxide, aluminum oxide and other electronic packaging materials, and it is easier to form and finish. High Temperature Applications Temperature stability and excellent resistance to thermal shock make BN the material of choice in the toughest high temperature applications such as plasma arc welding and semiconductor processing. Molten Metal Handling BN is inorganic, inert and is not wet by most molten metals and slags, nor does it react with halide salts or other reagents. These characteristics, combined with low thermal expansion, make it ideal for interface materials used in various molten metal processes.
