high wear resistant ceramic bolck detail description:

The alumina is the main material of the alumina ceramic and it is of better conductivity, mechanical strength and thermo stability. It is widely used in any area as its superior property. The alumina ceramic can be used in making IC board and isolative in industrial area.

excellent quality with competitive price
long operating life
high wear resistant
alumina content 92%

The common alumina ceramic are divided into 99%alumina, 95%alumina, 92%alumina, 90%alumina and 85%alumina according to the content of the alumina. The 99% alumina ceramic is mainly used in making higher temperature crucible, resistance furnace tube and some special anti-friction material, such as ceramic bearing, ceramic sealing element and water valve slice ect. The 95%alumina is mainly used in the component of wear decayed and wear resistant. The 85% alumina is mixed with the talc and enhance he electrical property and mechanical strength and can sealing-ined with MO, NB, some is used for the electrical vacuum plant.
