Tabular Alumina

Tabular Alumina is a pure sintered alpha-alumina material that has been fully densified by rapid-sintering without the use of sintering aids at temperatures in excess of 1900°C.

Tabular Alumina has characteristic large, well developed hexagonal tablet shaped alpha-alumina crystals. The excellent thermal volume stability and thermal shock characteristics can be attributed to its specific microstructure: low open porosity and large crystals with closed spherical pores,which are entrapped upon re-crystallization during rapid sintering.

Refractory is an unshaped refractory material which is prepared by ramming (manual or mechanical) method and hardened by heating at a higher temperature.Ramming materials into acid, neutral, alkaline three.

Parameter Index

Feature  

1.On the face in contact with liquid metal there is a dense sintered layer where tightness of liquid metal is quite perfect.

2.Thermal conductivity is lower than other refractoriness so the Thermal loses are less than any other kind of refractory.

3.Good resistance to temperature change.

4.Low cost in furnace lining.

5.Short heating and sintering time through dry preparation Of masses.
