Embodiment 1
[0031] 1) First, quartz, potassium feldspar, albite, borax, Bi 2 o 3 , Suzhou soil, lithium carbonate and other raw materials are prepared according to the following mass chemical composition ratios. SiO 2 :Al 2 o 3 :B 2 o 3 : Bi 2 o 3 : Li 2 O: Na 2 O:K 2 O=57:4:22:4:7:4:3.
[0032] 2) Dry mix and grind the above-mentioned powders, pass through a 60-mesh sieve to obtain the mixture, put it into a crucible, put it into an electric furnace and keep it at 1270°C for 20 minutes, take it out and pour it into water to quench to make a frit. Take out the frit from the water, put it into a ball mill after drying, and grind it finely. The mass ratio of control material (frit): ball: water is 1:1:0.8, pass through a 250-mesh sieve after grinding for 3 hours, and dry for later use. This powder is denoted as A material.
[0033] 3) Combine the above material A and Bi 2 o 3 , ZrO 2 And the mass ratio of Suzhou soil is A: Bi 2 o 3 : Suzhou soil = 82:7.4:7 ratio for batchi...
Embodiment 2
[0039] 1) First, quartz, potassium feldspar, albite, borax, Bi 2 o 3 , Suzhou soil, lithium carbonate and other raw materials are prepared according to the following mass chemical composition ratios. SiO 2 :Al 2 o 3 :B 2 o 3 : Bi 2 o 3 : Li 2 O: Na 2 O:K 2 O=58:5:23:3:6:3:2.
[0040] 2) Dry mix and grind the above-mentioned powders, pass through a 60-mesh sieve to obtain the mixture, put it into a crucible, put it into an electric furnace and keep it warm at 1280°C for 30 minutes, take it out and pour it into water to quench to make a frit. Take the frit out of the water, put it into a ball mill after drying, and grind it finely. The mass ratio of control material (frit): ball: water is 1:1:0.8, pass through a 250-mesh sieve after grinding for 4 hours, and dry for later use. This powder is denoted as A material.
[0041] 3) Combine the above material A and Bi 2 o 3 , ZrO 2 And the mass ratio of Suzhou soil is A: Bi 2 o 3 : Suzhou soil = 84: 7.2: 6 ratio for b...
Embodiment 3
[0045] 1) First, quartz, potassium feldspar, albite, borax, Bi 2 o 3 , Suzhou soil, lithium carbonate and other raw materials are prepared according to the following mass chemical composition ratios. SiO 2 :Al 2 o 3 :B 2 o 3 : Bi 2 o 3 : Li 2 O: Na 2 O:K 2 O=59:6:24:2:5:2:1.
[0046] 2) Dry mix and grind the above-mentioned powders, pass through a 40-mesh sieve to obtain the mixture, put it into a crucible, put it in an electric furnace at 1290° C. for 40 minutes, take it out and pour it into water to quench to obtain a frit. Take out the frit from the water, put it into a ball mill after drying, and grind it finely. The mass ratio of control material (frit): ball: water is 1:1:0.8, pass through a 250-mesh sieve after grinding for 3 hours, and dry for later use. This powder is denoted as A material.
[0047] 3) Combine the above material A and Bi 2 o 3 , ZrO 2 And the mass ratio of Suzhou soil is A: Bi 2 o 3 : Suzhou soil = 86:7:5 ratio for batching, and Bi ...
