Tone TAUSAGA vailaau Taulai atu i alumina vailaau

Boehmite

Faamatalaga puupuu:

A-AS-HC-GSA Boehmite o se vailaau taua mo le tapenaina o γ-Al2O3 ma α-Al2O3, faapitoa e faaaoga i vaega taua ma ona mea e feaveai, -O le mea, membranes porous ma vaivai malolosi, ceramics vevela maualuga ma isi


Faamatalaga oloa

pine o oloa

Faatinoga o Galuega oloa:
A gel sinasina (susu) po o le efuefu (mago), odorless, lē momose ma nontoxic. O se thixotrope i le tagata o le vaega maualuga crystalline mama, lelei GELATION ma meatotino caking malosi.
O se sima o le faapapaina o auala mo le lalolagi-e le masani semi-gaosi faamama molecular Y, o se sima i alumini silicate alava refractory, o se vaega taua i le faia o ethylene e ava malosi dehydration ma i le faia o ethane epoxy. E mafai foi ona faaaoga e pei o mea e masani ona maua mo le faagaoioia alumina ma isi aluminates.

Pseudoboehmite Talosaga:
1. FCC ma feaveai ai vaega taua hydrogenation.
2. sima i alumini silicate alava refractory.
3. metotia i le faia o ethylene e ava malosi dehydration ma i le faia o ethane epoxy.
4. Faaaogaina o mea e masani ona maua mo faagaoioia alumina ma isi aluminates.
