Aluminum oxide Usage And Synthesis
Chemical Properties white powder
Physical properties Al2O3 Colorless hexagonal crystal; refractive index 1.768; density 3.965 g/cm3 (at 25°C); mp 2072°C; bp 2980°C; insoluble in water α-Al2O3 Colorless rhombic crystal; mp between 2005 to 2025°C ; density 4.022 g/m3 ; hardness 9Moh γ-Al2O3 white microscopic crystal Al2O3•H2O colorless rhombic crystal; refractive index 1.624; density 3.014 g/cm3 Al2O3•3H2O white monoclinic crystal; refractive index 1.577; density 2.420 g/cm3 All forms are insoluble in water.
Uses Occurs in nature in abundance; the principal forms are bauxites and laterites. The mineral corundum is used to produce precious gems, such as ruby and sapphire. Activated aluminas are used extensively as adsorbents because of their affinity for water and other polar molecules; and as catalysts because of their large surface area and appropriate pore sturcture. As adsorbents, they are used for drying gases and liquids; and in adsorption chromatography. Catalytic properties may be attributed to the presence of surface active sites (primarily OH– , O2– , and Al3+ ions). Such catalytic applications include sulfur recovery from H2S (Clauss catalysis); dehydration of alcohols, isomerization of olefins; and as a catalyst support in petroleum refining.
Uses
  • As adsorbent, desiccant, abrasive,thickening and anti-caking agent;
  • As filler for paints and varnishes;
  • In manufacture of alloys,refractories, ceramic materials, electrical insulators and resistors, dental cements, glass, steel, artificial gems; in coatings for metals, etc.;
  • As catalyst for organic reactions.
  • As an insoluble carrier for mineral pigment, and is frequently mixed into mineral powder makeup. Because of its abrasive texture, many use these crystals to exfoliate and resurface the skin-particularly with Microdermabrasion.
  • As a chromotagraphic matrix; originally called Brockmann aluminum oxide when used for this purpose.
  • The minerals corundum (hardness = 9) and Alundum (obtained by fusing bauxite in an electric furnace) are used as abrasives and polishes;
  • In manufacture of cosmetic products like blush, powder foundation, lipstick and facial cleanser.
