Excerpt:
Boehmite is an important precursor for the preparation of γ-Al2O3 and α–Al2O3, Mainly used in catalyst and its carrier materials, coating material, porous membranes and soft abrasive, high temperature ceramics etc.
Product Performance:
A white gel (wet) or powder (dried), odorless, tasteless and nontoxic. It is a thixotrope with the characters of high purity crystalline phase, EXCELLENT GELATION and strong caking property.
It is a cement of the cracking catalyst for semi-synthetic rare-earth Y molecular sieve, a cement in aluminum silicate refractory fiber, a catalyst in making ethylene by alcohol dehydration and in making epoxy ethane. It also can be used as raw material for activated alumina and other aluminates.
Application:
1. FCC and hydrogenation catalyst carrier.
2. Cement in aluminum silicate refractory fiber.
3. Catalyst in making ethylene by alcohol dehydration and in making epoxy ethane.
4. Used as raw material for activated alumina and other aluminates.
