摘要：
Results of studies of Al2O3 suspensions made with different CaO and SrO contents are presented. The pH level increased with an increase in the content of CaO and SrO in the Al2O3 suspensions. The dynamic viscosity of the Al2O3 suspensions grew exponentially as the CaO content increased from 0.45 to 2.25 mol% and SrO, from 0.42 to 2.14 mol%. Reflections of CaAl12O19 and SrAl12O19 were observed in sintered materials of suspensions to which CaO and SrO, respectively, were introduced. These compounds had a lamellar structure.
