Densification of Zirconia with Borates.

Abstract

Sintering studies carried out on submicron CaO (6.5 percent by weight) stabilized ZrO powders, showed borate additions (1-10 percent by weight) to be effective densification aids. Densities greater than 99% estimated theoretical were obtained at 1200 degrees C/4 hours, with 2 percent by weight B2O3 or 5 percent by weight CaO borate (CaO.2B2O3; (CaO.B2O3)) additions to these powders.
