Type Insulating Ceramics

Material Boron Nitride

BN BORON NITRIDE CERAMICS / Technical Ceramics Manufacturer Hexagonal Boron Nitride Crucible

PRODUCT DESCRIPTION

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...

FAQ

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.

Q2: What types of ceramic do you supply?
>>> Alumina in purity from 90% to 99.7%, yttria stabilized zirconia (Y-PSZ), hot pressed boron nitride, machinable glass ceramic, boron carbide, silicon nitride, mullite and cordierite.

Q3: Can I machine the ceramics myself?
>>> The harder ceramics like alumna and zirconia will require diamond tooling but other materials like Machinable Glass Ceramic and Hot Pressed Boron Nitride can be machined. To get the right result it does take time, experience and semi-specialised tooling but it can be done and many of our customers take advantage of this when they need extremely fast solutions in-house.

Q4: Can I get a sample or purchase a small quantity?
>>> Yes, we are happy to supply small samples of material for you to test. We can also supply prototype quantities through to volume production to suit your needs.

Q5: How long will it take for you to send me a quote?
>>> This depends totally on the complexity of your requirements. For simple items such as bars and rods, we can generally supply a quotation within 24 hours.

Q6: What's the delivery time?
>>> For our standard products, like ceramic protection tubes and insulating rods, delivery time is normally 7 working days. For hot pressed boron nitride and machinable glass ceramic, it's about 10 working days. For customized products made of alumina, zirconia, boron carbide and silicon nitride, total producing time is about 30 working days.
