Black Ceramic Substrate / Black Ceramic Block :
Alumina substrates can withstand high temperature and maintain high
strength and hardness. Alumina plates also have superb performances
in electrical insulation, high chemical resistance and low thermal
expansion. We have various sizes of semi finished shapes in stock
and are able to conduct custom manufacturing for all kinds of
Black Ceramic Substrate / Black Ceramic Block Specifications
1. material : Alumina ceramic
2. Very small and very large size can be made
3. High temperature, good abrasive.
Refractory alumina ceramic substrate/ceramic plate is our main
product.Misson can supply high quality alumina plates with
Very small and very large sized plates can be made.
Fine grinding can made tight tolerance.
High temperature and abrasive resistance is good
1. High heat resistance : Alumina ceramic has excellent thermal
stability,which means that it is widely used in areas where
resistance to high temperatures is essential.
2. Good wear resistance : Alumina eramic is the material of choice
for wear parts.
3. High corrosion resistance : It is insoluble in water and only
slightly soluble in strong acid and alkaline solutions. Good
chemical stability of alumina leads to high corrosion resistance.
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.
