The ordering behaviour of albite in aqueous solutions at 1 kbar

摘要: Albite crystallized hydrothermally from gels of Ab100 and Ab90 (SiO2)10 (wt %) composition changes in degree Al, Si order with time to reach a steady value. The values are influenced by fluid gel as well temperature. Albites grown long experiments the presence NaOH excess SiO2 more ordered than albites similar pure water SiO2. This ‘catalytic’ effect declines temperature is increased above 600 ° C. Partially heated at 700 725 C decrease order. When °, 650 or 675 either increases very slightly, remains same depending on initially present.
