XTL Sintyron wholesale customized big 99 bn boron nitride ceramic rings


Boron nitride is an advanced synthetic ceramic material available in solid and powder forms. Its unique properties - from high heat capacity and excellent thermal conductivity to ease of processing, lubricity, low dielectric constant and excellent dielectric strength - make boron nitride a truly outstanding material. In its solid form, boron nitride is often called "white graphite" because it has a similar microstructure to graphite. However, unlike graphite, boron nitride is an excellent electrical insulator and has a high oxidation temperature. It has high thermal conductivity and good thermal shock resistance, and can be easily machined to close tolerances in almost any shape. Once machined, it is ready for use without additional heat treatment or firing operations.
