Beschreibungen/Notizen

• Application of new microbial dispersant to colloidal processing of fine powders of zirconia and alumina was conducted for obtaining fine-grained microstructures. Well-dispersed aqueous suspensions of the fine powders were prepared by adding appropriate amount of new microbial dispersant. The suspensions were characterized by measuring particle size, zeta-potential and rheological properties. Dense green bodies of zirconia and alumina were obtained by slip casting of the suspensions and further CIP treatment. Low-temperature densification was observed, and dense and fine-grained sintered bodies were obtained.
