Boehmite

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.

Pseudoboehmite 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.
