WebTetragonal Zirconia Polycrystal is limited in the presence of water. At even low to moderate temperatures, the tetragonal phase (t-ZrO 2) transforms to the monoclinic (m-ZrO 2), not only in a tiny region ahead of a crack, but all across the exposed surface. Because the monoclinic crystal structure is bigger by volume, this extensive phase WebMonocrystals of ZrCl were obtained by the reaction of ZrCl/sub 4/ (g) with a large excess of electropolished Zr in a sealed tantalum tube under a 600-800/sup 0/C gradient for 24 days.
