    Description of zirconia substrates  :
    Zirconia substrates can withstand high temperature and maintain high strength and hardness. zirconia plates also have superb performances in electrical insulation, high chemical resistance and low thermal expansion. We have various sizes of semi finished shapes in stock and are able to conduct custom manufacturing for all kinds of alumina components.

     

    Applications of alumina  substrates:
    •ziroconia substrates  plates are hard enough to become armor for personnel or vehicles.
    • The corrosion resistivity of alumina plates makes them a great material for chemical industry.
    • Used as a material for industrial furnaces due to its ability to maintain its hardness at high temperatures.
    • Used for making parts for CVD, ion implants, photolithography, and semiconductor parts.
    • In traditional industries, alumina ceramics are ideal for products such as injector tubes, gas nozzles and insulators.

     

     

    *This chart just demonstrates the typical properties of common alumina materials we use to produce our alumina parts. Please notice that the property for customized alumina parts could vary due to different process. Stanford Advanced Materials could provide alumina products produced under your specified instruction, or do the best to meet customers’ requirements.

     
    Alumina  Ceramic substrates Specifications
     
    1. material :  zirconia  
    2. Very small and very large size can be made
    3. High temperature, good abrasive.

    Refractory alumina ceramic substrate/ceramic plate is our main product.Misson can supply high quality alumina plates with competitive prices.

    Very small and very large sized plates can be made.

    Fine grinding can made tight tolerance.

    High temperature and abrasive resistance is good

     

     

    1. High hardness.

    2. High heat resistance : Alumina ceramic has excellent thermal stability,which means that it is

         widely used in areas where resistance to high temperatures is essential.

    3. Good wear resistance : Alumina ceramic is the material of choice for alumina wear parts.

    4. High electrical resistivity : Alumina is an electrically insulating material.

    5. High corrosion resistance : It is insoluble in water and only slightly soluble in strong acid and

    alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.
