Tabular fused alumina 2-5mm customized specifications
Tabular alumina is made of Al2O3,
after ingredients, grinding and forming, smelting in high temperature furnace
turned to α- Al2O3.
Production
feature:
Tabular alumina has good heat resistance and
good bulk temperature thermal shock capabilities. The crystal staggered plate
shape, to increasing the mechanical strength of the particles; interior
structure full of closed pores, high bulk density, low apparent porosity and
water absorption, to reducing the amount of fluid re-use productions; With good
physical properties like: high refractoriness, excellent thermal shock
resistance, low shrinkage and good thermal load strength etc. Meanwhile,
high-purity avoiding damage to machines.
