Abstract
A new energy-saving technology for the production of dead-burnt alumina has been studied, which differs from the existing ones in that the introduction of boric acid mineralizer simultaneously neutralizes the residual content of alkali. This makes it possible to carry out roasting in one stage. A method of chemical control over the content of α-modification of aluminum oxide during calcination of alumina has been proposed and tested. The method allows to monitor not only the quality of the obtained product, but also to quantify the content of corundum in alumina. The experimental results were confirmed by crystal-optical and X-ray diffraction studies.
