Collidal stability of zirconia-doped yttria-silica binary aqueous suspensions

摘要

Minor amounts of zirconia (up to 5 wt/100) were fused with yttria and their effect on water solubility of yttria, and colloidal stability of yttria-silica aqueous binary suspen- sions, was examined. It is shown that incorporate zirconia reduces the water sensitivity of yttria while maintaining the hydrophiolic nature of the surface. This fusion procedure makes yttria particles suitable for production of longlasting yttria-silica aqueous suspensions.
