Gibbsite - RRUFF Database: Raman, X-ray, Infrared, and Chemistry
Gibbsite, Al(OH)3, is one of the mineral forms of aluminium hydroxide. It is often designated as γ-Al(OH)3 (but sometimes as α-Al(OH)3. ). It is also sometimes called hydrargillite (or hydrargyllite). Gibbsite is an important ore of aluminium in that it is one of three main phases that make up the rock bauxite. WebOct 13, 2016 · RESULTS AND DISCUSSION. Zeta potential curves for gibbsite in the swamping electrolyte (KNO 3) indicate that the isoelectric point (IEP) (and the point of zero charge, pH pzc) of gibbsite is 10.55 ().This is also the common intersection point for the zeta potential measurements in 10 and 100 mmol L −1 KNO 3.The measured gibbsite IEP … WebDescription: Brownish yellow hemispheres of gibbsite on black matrix.
