Ceramic Tube for Vacuum Interrupter / Alumina Ceramic Threaded Tube
 
Mingrui Ceramic provides technical ceramic tubes 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.
 
Alumina as a fine ceramic material is widely used in a lot of industries. Alumina 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.

Material introduction:
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.
 
Available shapes:
Our Alumina Ceramic products can be made into different shapes like ceramic rods, ceramic bars, ceramic tubes/tubings, ceramic bushings/ceramic bushing, ceramic sleeves, ceramic seal rings, ceramic washers, ceramic ball valves, ceramic pistons, ceramic disks, ceramic plates/sheets/substrates or other customized shapes.
 
According to actual application and customer's requirement, the purities vary from 95%-99.7% and the forming methods will be different. The forming methods applied in our plant include dry pressing, isostatic pressing, injection moulding, extrusion moulding. With experienced engineers and talented workers, we are confident to offer high quality, high precision, complex components for customers worldwide.

 
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 .
