Pseudoboehmite
Chemical Formula: (Al2O3)*aH2O (1.0<α<2.0)
Products Description
Pseudoboehmite is non-toxic, tasteless, odorless, white colloidal (wet) or powdery (dry), high crystal purity, good molding performance, and has the characteristics of thixotropic gel.
Application
Pseudoboehmite is mainly used as raw material for catalyst carrier - active alumina, and also as molding binder for molecular sieve and silicate refractory fiber products, such as binder for semi-synthetic rare earth Y-type molecular sieve cracking catalyst, catalyst for alcohol dehydration to ethylene and ethylene oxide catalyst.
