High Fracture Toughness Zirconia Ceramic Tube Insulation Wear Resistant


Tag key words :  zirconia ceramic tube 


Mingrui Ceramic provides technical zirconia ceramic tube such as alumina tubes with high purity, tight dimensional tolerance and competitive price. Our alumina tube products with diameter from 1mm to 100mm and purity up to 99.8% will fulfil most of the requirements. Custom manufacturing for special shapes are always available.


Zirconia as a fine ceramic material is widely used in a lot of industries. Zirconia  tubes has superb performances in electrical insulation, high chemical resistance and low thermal expansion and these ceramic tubes are widely used in industrial ovens and machines. High purity alumina materials are excellent for making alumina components for CVD, ion implants, photolithography, and semiconductor manufacturing. In traditional industries, alumina tubes are ideal for products such as injector tubes and insulators. Alumina tubes are also widely used as protector for high temperature thermal couples.

Character of ceramic parts : 


1. High temperture ceramics -- crucibles , nozzles , lasers ,  furnace / kiln fixtures 

2. wear and corrosion resistant ceramics -- plates,  hosings , gages , caps / lids 

3. Electrical insulating ceramics --contact blocks , standoffs, fasteners , spacers

4. Good dimension stability , no deformation at any situation 

5. beatiful apprearance , never be aged and ocidated .


Industrial Ceramic Intriduction

Aluminium Oxide, Al2O3 is the most widely applied and cost effective technical ceramic material. It offers a combination of superior mechanical strength and electrical properties, wear resistance and corrosion resistance. The maximum working temperature is up to 1700 °C with relatively high thermal conductivity. It is also an electrically insulating material with a high electrical resistivity. The good corrosion resistance makes it insoluble in water and slightly soluble in strong acid and alkaline solution.
