| 摘要 |
This invention is directed to the formation of glass-ceramic articles which exhibit a yellow coloration in visible light and fluoresce with a yellow coloration while being exposed to ultraviolet radiation. The yellow coloration is produced through the incorporation of a color package comprising 0.05-0.5% V2O5, 0.25-5% CeO2, and 0.1-1% Tb2O3. When the glass-ceramic articles contain tetrasilicic fluormica as the predominant crystal phase, they are eminently suitable for use as dental prosthetic materials. |
