Abstract

The alkali-resistant porous glass was prepared from the Si02-B203-RO (R=Mg, Ca, Sr, Ba and Zn) system containing Zr02. The porous glass skeleton contained 2–3 mass% Zr02 and the alkali resistance was greatly improved over that of ordinary Vycor-type porous glass. Because of the high alkali resistance, the elimination of the colloidal Si02 and Zr02 gelated during the acid leaching of the phase-separated glass, was promoted and as a result, a very sharp pore-size distribution of porous glass was attained. In addition, the limit of the available pore size of porous glass was widely expanded.
