Frequently Asked Questions

What is the maximum working temperature of these plates?

The 99% alumina ceramic plates can withstand continuous operating temperatures up to 1600°C, with some grades reaching up to 1800°C depending on the specific application environment.

Can the ceramic plates be customized to specific sizes?

Yes, we offer full customization. Sizes range from 10x10mm up to 500x500mm, with thicknesses varying from 0.5mm to 30mm. Custom holes and grooves can also be added.

Is the material suitable for vacuum environments?

Absolutely. Our alumina ceramics feature zero outgassing in vacuum environments (up to <10⁻⁹ Torr), making them ideal for semiconductor and cleanroom applications.

How does alumina compare to steel in terms of wear resistance?

99% Alumina has a Vickers Hardness of ≥1500 HV, providing a lifespan that is often 10 times longer than steel in highly abrasive industrial environments.

What quality standards do these products meet?

Our products are compliant with ASTM F2880 and ISO 6474-1 standards. Each batch undergoes XRF purity verification and ultrasonic flaw detection to ensure maximum reliability.
