Advantages of Tabular alumina:
1)Tabular alumina price has high purity, good volume stability, minimal re-burning shrinkage, for the production of refractory or castable high-temperature treatment has good thermal shock stability and bending strength.
2) The crystal of tabular alumina price staggered plate shape, to increase the mechanical strength of the particles; interior structure full of closed pores, high bulk density, low apparent porosity, low water absorption, to reduce the amount of fluid re-use productions.
3) High refractoriness high corrosion resistance high erosion resistance, excellent thermal shock resistance, low shrinkage and good thermal load strength etc.
