As a professional company in advanced ceramic industries, HIGHBORN is manufacturing and supplying high quality and high precision ceramic components for clients from worldwide. Our ceramic products are widely used in various fields of automotive, metallurgy, machinery, electronic & electrical, food, chemical, medical and so on. With experienced engineers and talented workers, we are able to evaluate projects and drawings properly, make valuable suggestion, supply satisfying products. Our materials including:
- Alumina ceramic tube, alumina parts( 95% 96% 99% 99.5% 99.7% Al2O3 )
- Zirconia cermaic ( Yttria stabilized ZrO2 )
- Silicon Nitride ( GPS Gas pressure sintered & Hot pressed Si3N4 ) Silicon carbide
- Boron Carbide ( B4C )
- Boron Nitride ( Hot pressed BN )
- Machinable Glass Ceramic
- Steatite, cordierite
Zirconia is an extremely refractory material. It offers chemical and corrosion inertness to temperatures well above the melting point of alumina. The material has low thermal conductivity. It is electrically conductive above 600C and is used in oxygen sensor cells and as the susceptor (heater) in high temperature induction furnaces. With the attachment of platinum leads, nernst glowers used in spectrometers can be made as a light emitting filament which operates in air.
Specially shaped zirconia parts can also be produced according to customers' requirements and drawings.
Relying on powerful technical ability and normative quality management system, we can provide stable and precise silicon nitride parts and offer the best service to the customers.
