DX-AP-70-ρ
DX-AP-70-ρ is non-toxic, tasteless, odorless, white activated alumina powder. It is soluble in acid or alkali solutions and has strong water absorption in the air. it has few impurities, high purity, and does not contain a low eutectic phase. It has hydraulicity, and it can react with water to form a very strong Al (OH)3 gel.
A variety of applications including:
It is a new type of refractory material binder agent for high-temperature refractory materials. It can improve the refractory resistance and corrosion resistance to slag of refractory products. It can also be used as binder agent for activated alumina and other catalysts, as well as a binding agent for high-grade porcelain in the ceramic industry.
