Quality assurance:
Alumina ceramic is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance,but relatively low strength and fracture toughness.Alumina ceramics are generally white but may also be pink or ivory.The color is derived from either the sintering additives or impurities in the raw materials.
Other type of ceramic sheet/ plate/ substrate/ piece/ blank
· Ttz: Magnesia Partially Stabilized Zirconia (Zro2) Sheet/ Plate/
· Ytzp: Yttria Partially Stabilized Zirconia (Zro2) Sheet/ Plate/
· Zdy: Yttria Fully Stabilized Zirconia (Zro2) Sheet/ Plate/
· Silicon Carbide Sheet/ Plate/
· Silicon Nitride Sheet/ Plate/
Application
Ceramic block can be used for a device or equipment in the special
environment such as Power isolation, high temperature protection,
durable wear, high and low temperature impact etc...and for the
different device should be requiry different ceramic block shapes,
like: some device need the round sheet be machining 8 hole to
fasten to the box.
