Product FAQ's
How is an alumina substrate different from other ceramic materials?
An alumina substrate (often made from 95% to 99.8% aluminum oxide) offers excellent electrical insulation, high thermal conductivity, and resistance to chemical attack. Compared to other ceramics, alumina is more affordable and widely available in precise thicknesses for microelectronics and sensor applications.
What purity levels are available for aluminum oxide ceramic plates?
Most aluminum oxide ceramic plates come in purities from 95% up to 99.8% alumina, with higher purity improving electrical insulation and corrosion resistance. Applications like semiconductor processing or analytical equipment often require ≥99.5% purity.
Can alumina ceramic discs handle high temperatures?
Yes. Alumina ceramic discs can typically withstand continuous use at temperatures up to 1,600°C, depending on purity. This makes them ideal for high-temperature furnaces, kilns, and thermal analysis systems.
Are alumina substrates customizable in thickness and size?
Absolutely. Most suppliers provide alumina substrates and alumina plates in standard sizes, but they can also be custom-machined for specific dimensions, surface finishes, or even metallized patterns for electronic applications.
How do I choose between different alumina disc or plate options?
Consider the operating temperature, required electrical insulation, mechanical load, and chemical exposure. For critical applications, opt for high-purity grades to ensure maximum performance and minimal contamination.
Why is alumina preferred over other ceramics?
Alumina (aluminum oxide) offers a unique combination of high hardness, excellent dielectric properties, and good thermal conductivity at a relatively low cost compared to advanced ceramics like silicon nitride or zirconia.
