Abstract: High strain point glass as a new style glass has rapid development in recent years.High strain point glass has high impact resistance and high scratch resistance;it is widely used in CIGS solar energy substrate and touch devices.In this paper, the clarifying effects were investigated by different agent and content.Area refraction, mean bubble size and number of bubbles were analyzed quantitatively in the clarification process.An adequate mode of clarification is set up for high strain point glass, which can provide some guidance suggestions for glass production enterprises.

Key words: high strain point glass;refining agent;area refraction;mean bubble size;number of bubbles
