Slip for manufacturing ceramics and molded product for e.g. medical implants, comprises doped zirconia solid particles having tetragonal and monoclinic modification and specified mean agglomerate size, dispersed in liquid medium

摘要

A slip comprises a liquid medium, and doped zirconia solid particles having tetragonal and monoclinic modification, dispersed in the liquid medium. Doped zirconia solid particles have mean agglomerate size of 20-300 nm. The ratio of peak intensities between tetragonal and monoclinic modifications is 1.3-20. Independent claims are included for the following: (1) granules, which contain doped zirconia solid particles; (2) ceramics, which are formed using slip and/or granules. The ceramics contain structure containing mean grain size of less than 500 nm, and sintering density of more than 90%; (3) manufacture of slip; and (4) manufacture of black ceramics.
