Product Description

Polishing Alumina Ceramic Disc Insulating Alumina Round Plate


    The alumina plate is made of aluminum oxide ceramics. Alumina is a ceramic material with high thermal conductivity, compressive strength, and thermal shock resistance. It also has a low thermal expansion, making it a suitable material for furnace use, in the crucible, tube, and thermocouple sheath form.


    Aluminum oxide ceramic plates can withstand high temperatures and maintain high strength and hardness. Alumina ceramic plates also have excellent performances in electrical insulation, high chemical resistance, good were resistance and heat resistance, and low thermal expansion. YUBEI CERAMICS co., have various sizes of semi-finished shapes in stock and are able to customize kinds of alumina components for you.

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. What's the price for it?

    It depends. Prices are caculated by the drawing size and structure.


3. 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.


4. 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.


5. 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.


6. Can you do the finish maching?

    Yes, we have lathes, grinding machines, milling machines, carves-milling machines to make sure products' accuracy.
