Pore Size Distribution of Phase-separated Sodium Borosilicate Glass

Akio Makishima, Teruo SAKAINO

Abstract

For the purpose of investigating the structure of glass and initial stage of plase separation of sodium borosilicate glass, pore size distribution of porous glass which was obtained by acid leaching of sodium borosilicate glass heat-treated at 540°C was determined by nitrogen adsorption and direct transmission of electron microscope. Cranston-Inkley method was applied to calculate the pore size distribution and the calculation was performed by using electronic computer. The results obtained by both methods were in good agreement.
