[0021] The first step: preparation of bismuth silicate glass
[0022] Firstly, after cleaning and drying the quartz glass with a purity of 4-6N, put it into a ball mill jar and grind it to 300 mesh to make quartz glass powder; then, according to the molar ratio Bi 2 o 3 : SiO 2 = 1: 1 mix bismuth trioxide powder (content is 99.99%) and quartz glass powder and put into the agate emulsion ball mill jar and ball mill for 30min to obtain the batching material; secondly, add the batching material into the muffle furnace in advance In the high-purity alumina crucible with a cover, the temperature of the first feeding is 950°C, and the rest of the batch is added after holding the heat for 30 minutes, and the temperature is raised to 1080°C at 20°C / min. Stir the molten glass with a stainless steel rod for 1 minute every 1 hour; after the heat preservation is over, pour the molten glass into the middle of the rotating iron roller cooled by water, and make the molten glass into a glas...

[0028] The first step: preparation of bismuth silicate glass
[0029] Firstly, after cleaning and drying the quartz glass with a purity of 4-6N, put it into a ball mill jar and grind it to 300 mesh to make quartz glass powder; then, according to the molar ratio Bi 2 o 3 : SiO 2 = 1: 1 mix bismuth trioxide powder (content is 99.99%) and quartz glass powder and put into the agate emulsion ball mill jar and ball mill for 50min to obtain the batching material; secondly, add the batching material into the muffle furnace in advance In the high-purity alumina crucible with a cover, the temperature of the first feeding is 960°C, and the rest of the batch is added after keeping it for 25 minutes, and the temperature is raised to 1090°C at 22°C / min. Stir the molten glass for 1 minute, then pour the molten glass into the middle of the iron roller that is rotating on the ground and use water to cool it, and make the molten glass into a glass sheet with a thickness of 1-5mm during the co...

[0034] The first step: preparation of bismuth silicate glass
[0035] Firstly, after cleaning and drying the quartz glass with a purity of 4-6N, put it into a ball mill jar and grind it to 300 mesh to make quartz glass powder; then, according to the molar ratio Bi 2 o 3 : SiO 2 = 1: 1 mix bismuth trioxide powder (content is 99.99%) and quartz glass powder and put into agate emulsion ball mill jar and ball mill for 60min to obtain batching material; secondly, add batching material into the muffle furnace in advance In the high-purity alumina crucible with a cover, the temperature of the first feeding is 970°C, and the rest of the batch is added after holding the heat for 20 minutes, and the temperature is raised to 1100°C at 30°C / min. Stir the molten glass with a stainless steel rod for 1 minute every 1 hour; after the heat preservation is over, pour the molten glass into the middle of the rotating iron roller cooled by water, and make the molten glass into a glass with a thi...
