Embodiment 1
[0031] According to the proportioning of each component of the embodiment 1 of table 1, take respectively analytical pure raw material (B 2 o 3 、 Bi 2 o 3 , ZnO, MnO 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, keep it at 400°C for 1 hour, and then heat up at a rate of 2°C / m...
Embodiment 2
[0033] According to the proportioning of each component of the embodiment 2 of table 1, take respectively analytical pure raw material (B 2 o 3 、 Bi 2 o 3 , ZnO, MnO 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 990°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, raising the temperature in an electric furnace at a rate of 2°C / min, keeping it at 380°C for 1 hour,...
Embodiment 3
[0035] According to the proportioning of each component of the embodiment 3 of table 1, take respectively analytical pure raw material (B 2 o 3 、 Bi 2 o 3 , ZnO, MnO 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 960°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 Shaped, dried naturally, and then cut into the embryo body of the desired shape; place the embryo body at the part to be sealed, heat up at a rate of 2°C / min in an electric furnace, keep it at 370°C for 1 hour, and then heat it at...
