aluminum oxide usage and synthesis |
chemical properties | white powder |
general description | white odorless crystalline powder. water insoluble. properties (both physical and chemical) vary according to the method of preparation; different methods give different crystalline modifications. the variety formed at very high temperature is quite inert chemically. |
air & water reactions | insoluble in water. |
reactivity profile | aluminum oxide is chemically amphoteric (behaves as a weak acid in the presence of base and as a weak base in the presence of acid). may act catalytically. may cause the exothermic polymerization of ethylene oxide. may cause the vigorous polymerization of vinyl chloride [mca sd-75, 1970]. the degree of subdivision of the aluminum oxide may affect the vigor of such reactions. |
