    Abstract: This invention relates to the manufacture of translucent-totransparent glass-ceramic articles in the BaO-CaO-Al2O3 composition field which are nucleated with ZrO2 and/or V2O5 and/or Ta2O5. Such articles are thermally stable to temperatures up to about 1,400* C., exhibit good dielectric properties, are resistant to attack by alkali metal vapors, and transmit well in the infrared portion of the spectrum.

    Abstract translation: 本发明涉及BaO-CaO-Al2O3组合物领域中半透明透明玻璃陶瓷制品的制造,其用ZrO2和/或V2O5和/或Ta2O5成核。 这些制品在高达约1400℃的温度下是热稳定的,表现出良好的介电性能,耐碱金属蒸汽的侵蚀,并在光谱的红外部分良好地透射。
