Product Description
BN BORON NITRIDE CERAMICS / Technical Ceramics Manufacturer Hexagonal Boron Nitride Washer
Boron Nitride/BN is a synthetic technical ceramic material, which is available in powder, solid, aerosol and liquid forms. In solid form it can be machined easily with ordinary metalworking tools. Boron Nitride has out-standing thermal characteristics; high thermal conductivity and excellent thermal shock resistance. Boron Nitride in solid form is available in 3 grades, each having different characteristics
HPBN most common grade is manufactured by hot pressing. Its crystal structure is hexagonal. Due to the uniaxial densification method, the anisotropy of HPBN platelet structure is created. As a result of the anisotropy, different physical properties occur, parallel or perpendicular to the pressing direction. HPBN is non toxic and can be easily machined. |
Overview of typical properties: • Good electrical insulation; • High mechanical strength; • Excellent wear resistance; • Excellent corrosion resistance; • Low dielectric constant; • High using temperature; • High thermal shock resistance... | Overview of typical applications: • Pump seals and other components; • Wear resistant inserts; • Insulating washers or bushings; • Semiconductor components; • Aerospace components; • Automotive sensors; • Electrical or electronic insulators... |

Q1: What are advanced ceramics? >>> Advanced ceramics - also referred to as engineering, structural or technical ceramics - have been processed to be very pure and, in general, have superior properties to unrefined ceramics. Many are man-made, i.e. they do not occur naturally, e.g. silicon nitride, and their properties can be enhanced to produce very high strength at high temperatures, good corrosion resistance, etc. |
