Abstract

The results of studies of aluminum oxide suspensions made with different CaO and SrO contents are presented. An increase in the pH level was recorded with an increase in the content of calcium and strontium oxides in aluminum oxide suspensions. With an increase in the CaO content from 0,45 to 2,25 mol. % and SrO from 0,42 to 2,14 mol. % exponential growth of dynamic viscosity is observed in Al2O3 suspensions. In the sintered materials, in the suspension of which CaO and SrO were introduced, there are reflexes of the compounds CaAl12O19 and SrAl12O19, respectively. These compounds have a lamellar structure. Ill. 4. Ref. 15. Tab. 2.
