α-Alumina production from commercial alums
Source abstract
Abstract
Sinter–reactive powders of α–alumina have been prepared effectively by the decomposition of aluminium basic carbonates. In this work we have studied the urea CO(NH2)2 homogeneous hydrolysis method, applied to alum solutions, KAl(SO4)2 • 12H20, using various urea and alum ratios, to precipitate aluminium basic carbonates. The thermal decomposition of the aluminium precipitates, produces fine alumina powders that are suitable for ceramic purposes.
