Abstract
A process for the preparation of A-aluminium oxide comprises mixing of oxygen-containing sodium compound with aluminum oxide monohydrates and/or trihydrates and oxygen-containing lithium and/or magnesium compounds, dispersion and heating to 1100-1700 °C. With the purpose of efficiency process increasing, aluminum oxide monohydrate represents boehmite with a middle size of crystals is not less than 100 0A and with an average distance between base planes less than 6,8 0A, and aluminum oxide trihydrate represents bayerite with a middle size of crystals is not less than 100 0A and with an average distance between base planes less than 4,9 0A.
