| Abstract: | The effects of ZrO2 on the crystallinity of mica and microstructure of a machinable glassceramic were studied. It was found that ZrO2 is an effective nucleation agent in mica glassceramics. Stabilized by Ca2 , a lot of t--ZrO2 particles precipitate from ZrO2-mica glass-ceramics. The ZrO2 particles can effectively limit the growth of mica crystal and benefit the mechanical properties of glass-ceramics. |
