Summary: | The invention relates to a glazing composition for a porous dental zirconia article, the glazing composition comprising liquid, glass particles, fluorescing component(s) comprising europium, optionally hydrophilic silica nano-particles, and optionally hydrophobic silica nano-particles, wherein the fluorescing component(s) can be contained in the glass particles or as separate component. The invention also relates to a process for sintering a porous dental zirconia article with a glazing composition on its surface.
L'invention concerne une composition de vernissage pour un article poreux de zircone dentaire, la composition de vernissage comprenant un liquide, des particules de verre, un ou plusieurs constituants fluorescents comprenant de l'europium, éventuellement des nanoparticules de silice hydrophiles, et éventuellement des nanoparticules de silice hydrophobes, le ou les constituants fluorescents pouvant être contenus dans les particules de verre ou en tant que constituants séparés. L'invention concerne également un procédé de frittage d'un article poreux de zircone dentaire comprenant une composition de vernissage sur sa surface. |
