Alumina Ceramic Slat Positioning Ceramic Plate Insulating Ceramic
Alumina ceramic bar is developed and made of Aluminum Oxide
(Al2O3). Alumina is widely used in structural, electronics, medical
and electrical fields as one of the most important ceramic oxides.
Alumina ceramic parts are often used during high temperature
demanding and contamination-free reactions. It’s also a good
electrical insulator used as a substrate for integrated circuits.
Considering alumina’s price, high melting and boiling points, good
resistance, strong hardness and good electrical insulation, alumina
is widely spread and used all over the world in lots of industries.

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. 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.
6. 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.
7. Which is the nearest port?
Shanghai port is the nearest one from us. It takes about 2-3 hours
to get to shanghai port.
