    • A method of improving surface-dependent properties of phosphate glass such as durability and wear resistance without significantly affecting its thermal expansion coefficient is provided which comprises annealing the glass in a dry ammonia atmosphere at temperatures approximating the transition temperature of the glass. The ammonia annealing treatment of the present invention is carried out for a time sufficient to allow incorporation of a thin layer of nitrogen into the surface of the phosphate glass, and the treatment improves the durability of the glass without the reduction in the thermal expansion coefficient that has restricted the effectiveness of prior ammonia treatments. The improved phosphate glass resulting from this method is superior in wear resistance, yet maintains suitable thermal expansion properties so that it may be used effectively in a variety of applications requiring hermetic glass-metal seals.
    • 提供了一种提高磷酸盐玻璃的表面依赖性能的方法,例如耐久性和耐磨性,而不会显着影响其热膨胀系数,其包括在接近玻璃的转变温度的温度下在干氨气氛中退火玻璃。 本发明的氨退火处理进行足够的时间,使得能够在磷酸盐玻璃的表面中并入氮的薄层,并且处理提高了玻璃的耐久性,而不会降低热膨胀系数 限制了以前氨处理的有效性。 由该方法得到的改性磷酸盐玻璃具有优异的耐磨性,但保持适当的热膨胀性能,因此可有效地用于需要密封玻璃 - 金属密封件的各种应用中。
