Umkhiqizo Ukusebenza:
A gel emhlophe (ezimanzi) noma powder (omisiwe), ayinaphunga kunganambitheki futhi akunabo ubuthi. Kuyinto thixotrope nabalingiswa ephezulu msulwa crystalline isigaba, GELATION esihle futhi caking impahla eqinile.
Kuyinto okuqinisa ekwandeni ngokuhlaziya ngoba semi zokwenziwa ezingavamile-umhlaba Y ngesihlungo yamangqamuzana, usimende in aluminium silicate fibre refractory, kulethe ekwenzeni ethylene ngotshwala amanzi emzimbeni futhi ekwenzeni epoxy ethane. Iphinde ingasetshenziswa njengendlela impahla eluhlaza for alumina isebenze nezinye aluminates.
Pseudoboehmite Isicelo:
1. I-FCC kanye hydrogenation kulethe yenethiwekhi.
2. Usimende in aluminium silicate fibre refractory.
3. Catalyst ekwenzeni ethylene ngotshwala amanzi emzimbeni futhi ekwenzeni epoxy ethane.
4. Isetshenziswa njengesici impahla eluhlaza for alumina isebenze nezinye aluminates.
