Effect of Al2O3 on Surface Tension of the SiO2-Al2O3-RO-R2O Glass System
Abstract:
This study selected high alkali aluminosilicate glass as the research object. It’s belongs to the SiO2-Al2O3-RO-R2O glass system. By changing the content of Al2O3 in the SiO2-Al2O3-RO-R2O glass system, designed five basic glass formula. Using conventional melting method prepared the high alkali aluminosilicate glass. In the case of the same heat treatment, the glass formulations are the most important factor in the glass surface tension. Using the glass surface tension measuring instrument, focus on the content of Al2O3 on the glass surface tension’s effects law. The results show that the high alkali aluminosilicate glass’s surface tension are increase with the increase of Al2O3 content. The relation between glass surface tension and the content of Al2O3 conforms to the formula Y=290+6.5WAl2O3, Al2O3 factors influence the surface tension of the glass is 6.5.
