Investigation the effect of MgO and Temperature on Phase separation and porosity of Borosilicate Glasses for use in Glass Membranes
Abstract:   (11216 Views)
The investigation of glass membrane nowadays is very important branch in scientific researches, has a differences sides. One of them is the change in composition of glass membrane for control the phase separation and pore size. The important group of usage composition in glass membrane is the borosilicate glass former. The effect of additives such as CaO and BaO on the these systems has been investigated in some scientist`s researches. In this research, the effect of MgO and temperature variation on these compositions and the phase separation quality and their pore size was investigated. Addition of 0, 2, 4 and 6 percent of MgO with change in heat treatment temperature in four temperatures 670oC, 690oC, 710oC, 730oC was investigated. For preparation the glass membranes, after melting the primary composition, the molten glass was cooled and then annealed. Productions heat treated in four temperatures and then etched. After analyzed the samples with SEM, leaching the samples and then samples analyze with porous analysis such as BET and BJH. At the end receiving to mean pore size about 12 nm and although pore size distribution from 5 to 100 nm was the important results of this research.
Keywords: Glass membrane, Borosilicate glasses, MgO
