Hexagonal 99.7% Customized Boron nitride ceramic Parts

The main features of the boron nitride ceramic parts

1. BN ceramic elements owns heat resistance which are fired under high temperature and high pressure
2. BN ceramics is chemically inert to most molten metals and is used in non-oxidizing atmospheres up to 2800 °C.

3. Boron nitride ceamic have great good thermal conducitive, electrical insulation and chemical properties.
4. BN the advantages of absorbing neutrons, infrared ray penetration, high temperature lubricity and processability

5. Easily machinable characteristic, it's easier to achieve a high precision accurancy, such as 0.01mm.

The description of boron nitride ceramic elements

Boron Nitride Ceramics can be used in the manufacture of smelting semiconductors for high temperature containers for metallurgy, semiconductor heat-dissipating insulation parts, high-temperature bearings, thermowells and glass forming dies, etc. It can also be widely used in electronics, metallurgy, chemical, atomic energy and aerospace.

The application of boron nitride ceramic parts

Boron nitride ceramic parts are widely used as high temperature electric furnace components (high temperature insulation bushes, etc.), metal
evaporation crucibles, various devices for molten metal or glass, precious metal or special alloy casting mold parts, high temperature support and other stressed components, molten metal transport pipes, nozzles ect.
