Abstract: Thermally stable, mechanically strong microporous glass articles with large pore volumes, surface areas, and varying pore sizes, and methods for making such articles are disclosed. In particle form, such as beads, the microporous glass articles are useful as catalyst supports in applications such as petroleum catalytic refiners, chemical processes and motor vehicle catalytic mufflers. The mechanical strength and the dimensional stability of the microporous glass articles at elevated temperatures can be improved if the articles are preshrunk, such as by brief exposure to high temperatures, before their intended use, and can be improved even further if treated with certain metal oxides.

Abstract translation: 公开了具有大孔体积，表面积和不同孔径的热稳定的机械强度微孔玻璃制品及其制造方法。 在颗粒形式如珠粒中，微孔玻璃制品可用作催化剂载体，例如石油催化精炼机，化学工艺和汽车催化消声器。 如果在预期的使用之前，如在短时间暴露于高温下预制物品，则可以提高微孔玻璃制品在高温下的机械强度和尺寸稳定性，并且如果用某些金属氧化物 。
