Buy low price Wedge Tabular Alumina with good volume stability and thermal shock resistance, high purity and refractoriness, excellent mechanical strength, abrasion resistance and corrosion resistance against slag and other substances
WTA001 - Tabular Alumina is a pure material sintered at super-high temperature without Mgo and B2O3 additives, its microstructure is a two-dimensional polycrystalline structure with well-grown large tabular a-Al2O3 crystal.
Tabular alumina has a lot of small closed pores in individual crystal, Al2O3 content is more than 99%. Therefore Sundar Tabular Alumina has good volume stability and thermal shock resistance, high purity and refractoriness, excellent mechanical strength, abrasion resistance and corrosion resistance against slag and other substances.
Wedge Tabular Alumina is a key raw materials to produce high-quality monolithic and shaped refractories, widely used in ladle castables, purge plugs, nozzles for CC, and in kiln furniture, rollers, special ceramics, abrasives as well.
