Applications of alumina  substrates:
•Alumina 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.
