High temperature creep of two zirconia toughened alumina ceramics, fabricated by powder processing and sol-gel precursors processing, has been studied in order to determine plastic deformation mechanisms. Compressive creep tests were carried out between 1300 and 145O"C, under stresses from IO to I50

The crystalline structure and dielectric properties of Ba x Sr 1-x TiO 3 ceramics with x = 0.45, 0.5, 0.6, 0.65, 0.8, 0.9 were investigated. The a-and c-axis lattice constants of Ba x Sr 1-x TiO 3 ceramics were calculated and it is found that the crystal structures are tetragonal phase when x β₯ 0.65
Inhomogeneous ceramics of hydroxyapatite (HA) were prepared by sintering briquettes in which an inhomogeneous distribution of density was made by pressing HA powder into a die with rough walls. The resulting sample of such a ceramic is a hard thin shell with a loose core, and it is characterized by
