Aluminum oxide, 20% in H2O, colloidal dispersion


Chemical Properties

0.05 Micron Particles
Miscible with ethanol.


Effective in high temperature refractories as a stable binderAluminum oxide, 20% colloidal dispersion is used in dessicators, ceramics, coating materials and electrical insulators. It is an ingredient in sunscreen, and sometimes present in cosmetics such as blush, lipstick, and nail polish. Aluminum oxide is a catalyst in the claus process in hydro desulfurization and some Ziegler-Natta polymerizations. It is widely used as an abrasive, in the automotive industries, cosmetic industries and fiber materials. It is a medium for chromatography in some sodium vapor lamps. It is used in ultrafine acid side polishing slurries.


Exists as pseudo-Boehmite with chemical composition corresponding to (AlO(OH) or Al{2}O{3}.H{2}O). Particle charge (+), pH 4, Specific Gravity 1.19, viscosity 10cps, counter ion (mol/mol) 0.049 No{3}Incompatible with halogenated hydrocarbon, strong bases, strong acids, vinyl compounds, ethylene oxide, chlorinetrifluoride, oxygen difluoride, sodium nitrate, alkali and alkaline earth metals.
