High Specific Surface Al2O3 Pseudoboehmite As Cement For Aluminum Silicate Refractory Fibre
china professional pseudoboehmite supplier
Pseudo-boehmite is white powder with high purity, low pile, large pore volume, high specific surface and good compatibility. It can be easily decentralized and soluble in the acid and alkali solution. It can become highly active alumina after low-temperature roasting and dehydration.
Mainly used as raw materials for the production of catalyst carrier, activated alumina, also as molecular sieve, and as cement for aluminum silicate refractory fibre, for examples, as a cement of the catalyst for semi-synthetic rare earth cement of the catalyst for semi-synthetic rare earth Y molecular sieve cracking, catalyst in making ethylene by alcohol dehydration and EO.
