Specifications

Can be used as high temperature (low cement or cement) refractory castable shaping binder, especially without cement castable, 

Hydrated alumina (ρ- Al2O3), also called hydraulic aluminum oxide powder, non-toxic, tasteless, odourless, white powder, soluble in acid or alkali solution, in the air has a strong water absorption performance.With hard water.With water hydration reaction can generate aluminum hydroxide gel.Can be used as high temperature (low cement or cement) refractory castable shaping binder, especially without cement castable, such as aluminum ladle with silica, alumina magnesia castable and the tapping ditch with aluminum silicon carbon amorphous refractory castable, etc.Improve the refractoriness, slag corrosion resistance of refractory products, don't fall at the same time, the temperature in both strength and other properties. Improve ladle, iron ditch, etc. The service life of refractory material, reduce the cost.Can also be activated alumina and other raw materials and catalyst forming adhesive, preparation of alumina crucible high aluminum ceramic binder, and the combination of high-grade porcelain ceramic industry.
