Several glasses in the Na/sub 2/O-CaO-P/sub 2/O/sub 5/, Na/sub 2/O-BaO-P/sub 2/O/sub 5/, Na/sub 2/O-Al/sub 2/O/sub 3/-P/sub 2/O/sub 5/, and Li/sub 2/O-BaO-P/sub 2/O/sub 5/ systems devitrified to form glass ceramics upon heat treatment. One mol % of TiO/sub 2/, ZrO/sub 2/, Y/sub 2/O/sub 3/, La/sub 2/O/sub 3/, Ta/sub 2/O/sub 5/, as nucleating agents included in a 39 Na/sub 2/O.10 BaO.50P/sub 2/O/sub 5/.1 nucleating agent (mol %) glass caused a larger volume of crystal phases to form compared to the undoped glass. Grain sizes generally increased with field strength of nucleation cation.
