Embodiment 1
[0030] Embodiment 1: Preparation and sealing of materials
[0031] According to the proportioning of each component of embodiment 1 in table 1, take a certain amount of analytically pure raw material (B 2 o 3 、 Bi 2 o 3 , ZnO, SnO 2 ), use a planetary ball mill for 24 hours to mix evenly; then put the powder into a platinum crucible, place it in the air atmosphere of a box-type resistance furnace, heat it to 1000°C at 3°C / min, and keep it warm for 1 hour; then, take out the crucible, Pour the melt into deionized water for rapid cooling, and dry to obtain fragments of glass melt; grind and pass through a 100-mesh sieve to obtain glass powder. Mix glass powder with polyvinyl alcohol, fish oil, ethanol and toluene (80%, 2%, 1%, 10%, 7% by weight) to form a slurry, and disperse evenly in a ball mill; tape casting, natural Dry, then cut into the embryo body of the desired shape; place the embryo body on the part to be sealed, heat up in an electric furnace at a rate of 2°C / min...

[0032] Embodiment 2: Preparation and sealing of materials
[0033] According to the proportioning of each component of embodiment 2 in table 1, take a certain amount of analytically pure raw material (B 2 o 3 、 Bi 2 o 3 , ZnO, SnO 2 ), and mixed evenly with a planetary ball mill for 24 hours; then put the powder into a platinum crucible, place it in the air atmosphere of a box-type resistance furnace, heat it to 980°C at 3°C / min, and keep it warm for 1 hour; then, take out the crucible, Pour the melt into deionized water for rapid cooling, and dry to obtain fragments of glass melt; grind and pass through a 100-mesh sieve to obtain glass powder. Mix glass powder with methylcellulose, polyvinyl alcohol, n-butanol and acetone (82%, 2%, 2%, 8%, 6% by weight) to form a slurry, and disperse evenly in a ball mill; Stretching, drying naturally, and then cutting the embryo body into the desired shape; placing the embryo body on the part to be sealed, heating it in an electric furn...
Embodiment 3
[0034] Embodiment 3: Preparation and sealing of materials
[0035] According to the proportioning of each component of embodiment 3 in table 1, take a certain amount of analytically pure raw material (B 2 o 3 、 Bi 2 o 3 , ZnO, SnO 2 ), use a planetary ball mill for 24 hours to mix evenly; then put the powder into a platinum crucible, place it in the air atmosphere of a box-type resistance furnace, heat it to 950°C at 3°C / min, and keep it warm for 1 hour; then, take out the crucible, Pour the melt into deionized water for rapid cooling, and dry to obtain fragments of glass melt; grind and pass through a 100-mesh sieve to obtain glass powder. Mix glass powder with epoxy resin, polyacrylamide, isopropanol and toluene (84%, 1.5%, 0.5%, 9%, 5% by weight) to form a slurry, and disperse evenly in a ball mill; casting Shaping, drying naturally, and then cutting into the embryo body of the desired shape; place the embryo body on the part to be sealed, heat up at a rate of 2°C / min ...
