99% Insulating Alumina Ceramic Plate Advanced Ceramic Plate
Our factory provides a full range of Oxide and Carbide advanced ceramic materials with different combinations of mechanical, thermal, and electrical properties for supporting a wide spectrum of high-tech applications.
- Mechanical: Advanced ceramic materials are engineered for performance, with excellent mechanical strength characteristics including hardness, density, and fracture toughness, enabling application-specific mechanical requirements to outperform metals and polymers.
- Thermal: Thermal properties characterize how a material reacts to changes in temperature. Advanced ceramics can be used to withstand and perform at extremely low and excessively high temperatures.
- Electrical: The composition of most advanced ceramics makes them highly effective electric insulators. This is by far the most common use of all advanced ceramics. But some ceramics can be used as semiconductors or engineered to work with processes when the demand arises.

Aluminum Oxide Ceramic Plate
FAQ:
1. Are you a factory?
Yes, we're a factory producing industrial ceramics professinally. Our main products are alumina ceramics, zirconia ceramics and sic ceramics.
2. Can you do the finish maching?
Yes, we have lathes, grinding machines, milling machines, carves-milling machines to make sure products' accuracy.
3. What's the size of it?
Products are always customized according to drawings or samples. Diameter and height within 500mm are available.
4. What's the price for it?
It depends. Prices are caculated by the drawing size and structure.
5. What's the production process?
Our products are made mainly in cold isostatic pressing, dry pressing and hot press moulding technique. Hot press moulding technique, which was used to shape small and medium size and complicated structure ceramic, is a favorable method.
6. How about the delivery?
Generally speaking, a ceramic production needs about 30 days to finish. Some special products maybe take a longer time. For some simple products, maybe 10-15 days is ok.
7. How's the packing?
The usual packing is cartons, wooden cases, or pallets. Ceramics are fragile products, will use some breakage-proof materials to protect them.
8. Which is the nearest port?
Shanghai port is the nearest one from us. It takes about 2-3 hours to get to shanghai port.
