Embodiment 1
[0020] Weigh the purity of 4N, the average particle size of 1.0 microns ZnO 1000 grams of powder, add 1000 grams of Sn with an average particle size of 5 microns O 2 Powder, add 700g of deionized water and 10g of triethanolamine, 20g of polyvinyl alcohol organic additives, ball mill and mix for more than 12 hours, the slurry is spray-dried and granulated to obtain a raw material with an average particle size of 50 microns, using cold isostatic Press 150Mp to form a green body with a relative density greater than 55%. The green body is kept in an air furnace at 500°C for 4 hours to remove organic additives, and the temperature is raised to 1500°C to sinter and compact to obtain a ceramic semiconductor with a relative density of 98%. The sintered body is processed and ground to a TZO material with a diameter of 76 mm and a thickness of 6 mm. DC magnetron coating is performed in a SIM560 magnetron sputtering machine with a power of 100W and Ar 2 The pressure is 0.6Pa, the temp...

[0022] Weigh the purity of 4N, the average particle size of 1.0 microns ZnO Powder 1000 grams, adding weight 250 grams average particle size 5 microns Dy 2 O 3 Powder, add 35% of the total weight of deionized pure water and mix it with a ball mill for more than 12 hours, dry it through a 100-mesh sieve, put the powder into a high-strength graphite mold with a BN coating within an inner diameter of 120 mm, and place it in a hot-press furnace Hot pressing and sintering at 1000°C for 1 hour, cooling and demoulding mechanical processing to obtain a TZO material with a relative density of 95% and a diameter of 76 mm and a thickness of 6 mm. Coating in a SIM560 magnetron sputtering machine, power 100W, Ar 2 The pressure is 0.6Pa, the temperature of the glass substrate is normal temperature, the sputtering process is stable and easy to control the sputtering, the thickness of the film measured by XP-1 step meter is 200 nanometers, and the visible light transmittance of 400-700 n...
Embodiment 3
[0024] Pure water, methacrylamide monomer, N-N , Dimethylbisacrylamide is fully dissolved at a ratio of 100:16-18:0.6-1 to form a premix, and an appropriate amount of tetramethylammonium hydroxide (0.1-1.5%) is used as a dispersant, and the weighing purity is 4N, the average Particle size 2 microns ZnO Powder 1000 grams, add weight 650 grams average particle diameter 5 micron Sn O2 Powder, stir the raw material powder to make slurry, the solid phase content of the powder in the slurry is 55-65%, pour the prepared slurry into the ball mold machine and use zirconia balls as the medium ball mill for more than 12 hours, then add 0.1 - 1% volume of organic degassing agent such as n-butanol, 0.1-1.5wt‰ tetramethylethylenediamine catalyst and 0.01-0.5wt‰ ammonium persulfate initiator, stirring and degassing in a vacuum mixer for 20 minutes, passing through 100 mesh Sieve pouring into a non-porous mold with a diameter of 150 mm. After the wet green body is solidified and demolded, ...
