Embodiment Construction
[0006] According to SiO 2 69-70%, AL 2 o 3 Accounting for 1~2%, B 2 o 3 Accounting for 1 to 1.5%, B 2 O accounts for 8-9%, K 2 O accounts for 2 to 3%, Na 2 O accounts for 9-10%, CaO accounts for 1-1.5%, MgO accounts for 0-1%, S 2 O accounts for 1.5-3%, Li 2 O accounts for 1.5-2% of the component ingredients, weighing of raw materials→stirring→feeding→melting, clarification, homogenization in electric furnace→drawing tube forming→fine cutting round mouth→inspection and packaging→storage. Thereby obtaining lead-free special glass for energy-saving lamps with a linear expansion coefficient of 92±2% and a softening point of 640±10°C.
