Description:
Alumina ceramic plates can withstand high temperature and maintain
high strength and hardness. Alumina 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:
• Alumina 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.
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
