[0021] Preparation of glass powder: Precisely mix 1 kg of bismuth oxide 60%, silicon oxide 25%, aluminum oxide 5%, boric acid 6%, and zinc oxide 4% in a polytetrafluoroethylene tank according to the mass percentage, and then seal the polytetrafluoroethylene The ethylene tank was placed on an eight-roller ball mill for 1.5 hours of mixing; after the mixing was completed, the resulting mixture was put into a 2L quartz crucible, and placed in a 1200°C resistance furnace for heat preservation and melting for 1.5 hours, and the obtained glass solution was water-quenched to obtain glass slag. Put the glass slag into a 3L zirconia ball mill jar, add pure water according to the mass ratio of material to water at 1:1, put it on an eight-roller ball mill and grind it until the particle size D50≤1.5μm, pour it out, and use a 600-mesh screen After sieving, put the sifted liquid into an oven and dry at 120°C for 24 hours to obtain Bi-Si-B glass powder; refill the Bi-Si-B glass powder into a...

[0025] Preparation of glass powder: Precisely mix 1 kg of bismuth oxide 55%, silicon oxide 30%, aluminum oxide 4%, boric acid 9%, and zinc oxide 2% in a polytetrafluoroethylene tank according to the mass percentage, and then seal the polytetrafluoroethylene Put the ethylene tank on an eight-roller ball mill for mixing for 1.5 hours; after the mixing is completed, the resulting mixture is put into a 2L quartz crucible, and placed in a resistance furnace at 1100°C for 1 hour of heat preservation and melting. The obtained glass solution is water-quenched to obtain a glass body. The glass body is broken into glass slag, and the glass slag is put into a 3L zirconia ball mill jar, and pure water is added according to the mass ratio of material to water of 1:1, and placed on an eight-roller ball mill until the particle size D50≤1.5μm, then poured out, and used Sieve through a 600-mesh sieve, put the sieved liquid into an oven and dry at 120°C for 24 hours to obtain Bi-Si-B glass powde...
