Tabular Alumina
Description：
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.
Hiaxu/Sicheng is your best choose as refractory material/ceramic material and
insulating materials.
Application:
Tabular
alumina is an ideal refractory material, either can be used in various
refractory alumina, or can be add in other unshaped refractories
