Tabular alumina is a pure sintereda-alumina material that has been densified by rapid sintering without the use of sintering aids at temperature in excess of 1900. It has the characteristics of low open porosity and large crystals with closed spherical pores which are trapped upon re-crystallization during rapid sintering. Tabular alumina is of high refractoriness, excellent thermal shock resistance, fantasticanti-creeping and anti-stripping performance. As the essential refractory raw material finally applied in the iron and steel industry, it is most widely used in the refractory castables for ladles, precastings as porous plugs, seating bricks,sliding plates, long nozzles, stoppers. As the primary choice of refractory aggregate, it is also widely used in a variety of industries such as foundry,petrochemical, ceramic.
