It has been established that the high temperature of decomposition of amorphous Al(OH)3 makes it possible to directly sinter corundum ceramics from aluminum hydroxide, bypassing the stage of its preliminary thermal dehydration. Cold isostatic pressing at pressures of 200, 600, and 1000 MPa was used to make compacts with a density of 62, 69, and 79 % of the theoretical density. The temperature dependence of the shrinkage of compacts of amorphous Al(OH)3 as a function of the pressure of cold isostatic pressing has been studied. A region of intense shrinkage was found in the region of 1050 – 1150 ?C, which coincides both with the temperature of complete decomposition of amorphous Al(OH)3 and with the ???-Al2O3 transition.
