Abstract
Compaction behavior of two batches of yttria-stabilized zirconia powders containing different kinds of agglomerates were investigated with the help of pore size distribution measurements for powders and compacts. The pore structure changes during the powder compaction show that the weakest agglomerates obtained with the total dewatering by ethyl alcohol are eliminated in compaction at not higher than 100 MPa and are independent of calcination temperature. Agglomerates in untreated powder with alcohol are strong and cannot be broken at even 500 MPa. Different compaction behaviors of agglomerates are thought to be due to the whole different process taking place during drying and decomposition of the untreated and treated powders.
