Metallurgical Tabular Alumina Chemical Insulating Fire Brick Support
Tabular Alumina
1 . Product Description
---- Tabular Alumina is a pure material sintered at super - high temperatures without MgO and B2O3 additives,Its microstructure is a two - dimensional polycrystalline structure with well - grown large tabular α - Al2O3 crystals . Tabular Alumina has a lot of small closed pores in individval crystal , Al2O3 content is more than 99 % .Therefore it has good volume stability and thermal shock resistance , high purity and refractoriness , excellent mechanical strength , abrasion resistance against slag and other substances.
---- Tabular Alumina is a key raw material to produce high - quality monolithic and shaped refractories , widely used in ladle castables , nozzles for CC , and in kiln furniture, rollres,special ceramics , abrasives as well .
