The performance of lightweight high aluminum casting material is decided by the size and characteristics of chemical surface properties of the microporous. Compared with other porous materials, lightweight high alumina casting material has the following properties:

1. Excellent, even in the highly open pores, tortuous process, high surface area, room temperature and temperature change of high strength, low density, good thermal shock resistance, high temperature resistance, chemical corrosion resistance, good filtration and adsorption performance and can be used as catalyst carrier, microbial immobilization, reverse osmosis membrane properties, micro foaming etc..
2. High aluminum pouring material prepared by different processes and its performance is different, different performance determines the different applications. The uniformity of light high alumina casting materials can produce all kinds of filters, separation device, fluid distribution element, mixed element, element and element such as exudation.
3. Lightweight high alumina castable with high strength, long service life, heat insulation, high temperature resistance, good thermal shock resistance and erosion resistance etc.
