Properties: Approximate characteristics of native aluminum oxide: White cryst powder. Very hard, about 8.8 on Moh's scale. An electrical insulator; electrical resistivity at 300° about 1.2 ′ 1013 ohms-cm. When heated above 800° it becomes insol in acid and specific gravity increases from 2.8 to 4.0. Insol in water. Very hygroscopic.
CAUTION: Potential symptoms of overexposure by direct contact are irritation of eyes, skin and respiratory system. See NIOSH Pocket Guide to Chemical Hazards (DHHS/NIOSH 97-140, 1997) p 12.
Use: As adsorbent, desiccant, abrasive; as filler for paints and varnishes; in manuf of alloys, ceramic materials, electrical insulators and resistors, dental cements, glass, steel, artificial gems; in coatings for metals, etc.; as catalyst for organic reactions. 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 manuf of refractories.
