Abstract:
The structural and mechanical properties of alumina modified with La and Ce ions were studied at different temperatures (873-1573 K) and contents of additives. The maximum stabilization effect on the specific surface area (S-sp) was observed at 1173-1473 K with the addition of 5 wt % La2O3. The stabilization of the porous structure of modified samples takes place at T > 1173 K. The mechanical strength of granules incorporating lanthanum and cerium ions increased with temperature. The results obtained allow one to determine the relationships between previous data on the influence of lanthanum and cerium ions on the polymorphous transformations in alumina dependent on the conditions of thermal treatment, the structure, and mechanical properties of modified alumina.
