Decomposition of al oh 3

WebAluminum trihydroxide, Al (OH)3, (gibbsite) is thermally decomposed at a temperature in the range of 375° to 450°C to release water vapor and form a partially dehydrated A1 2 0 3. Complete dehydroxylation is not allowed to occur. The product is a powder still capable of losing 4 to 7% on ignition at high temperature.
