Embodiment 1
[0027] A preparation method of blue nano indium tin oxide powder, comprising the following steps:
[0028] 1) Add InCl 3 and anhydrous SnCl 4 It is 0.2mol / L solution that the concentration of metal ion is mixed with distilled water, then the ammoniacal liquor that molarity is 0.2mol / L is dissolved in distilled water to make alkaline solution, then the described alkaline solution that makes is with the concentration of 10ml / min Add dropwise to the 0.2mol / L solution at a dropping rate, and keep stirring, control the reaction temperature to 60°C, stop dropping when PH=7.1, continue to react for 30 minutes, and prepare a white indium tin oxide precursor;
[0029] 2) Wash the white indium tin oxide precursor prepared in step 1) three times with water and twice with ethanol, and then put it into a drying oven for drying at a temperature of 60°C. Grinding to obtain intermediate product B;
[0030] 3) Put the intermediate product B obtained in step 2) into a crucible, and then put ...
Embodiment 2
[0035] A preparation method of blue nano indium tin oxide powder, comprising the following steps:
[0036] 1) Add InCl 3 and anhydrous SnCl 4 It is mixed with distilled water to make a metal ion concentration of 0.2mol / L solution, then the urea with a molar concentration of 1mol / L is dissolved in distilled water to make an alkaline solution, and then the alkaline solution made is dripped at 50ml / min Add it dropwise to the 0.2mol / L solution at an accelerated rate, and keep stirring, control the reaction temperature to 60°C, stop the dropwise addition when PH=7.1, and continue the reaction for 30 minutes to prepare a white indium tin oxide precursor;
[0037] 2) Wash the white indium tin oxide precursor prepared in step 1) three times with water and twice with ethanol, and then put it into a drying oven for drying at a temperature of 80°C. Grinding to obtain intermediate product B;
[0038] 3) Put the intermediate product B obtained in step 2) into a crucible, and then put it...
Embodiment 3
[0043] A preparation method of blue nano indium tin oxide powder, comprising the following steps:
[0044] 1) Add InCl 3 and anhydrous SnCl 4 It is 0.2mol / L solution that metal ion concentration is mixed with distilled water, then the aqueous solution of ammonium bicarbonate that molar concentration is 0.5mol / L is dissolved in distilled water to make alkaline solution, then the described alkaline solution that makes is with Add dropwise at a rate of 10-50ml / min into the solution with a concentration of 0.2mol / L, and keep stirring, control the reaction temperature at 60°C, stop dropping when PH=7.1, continue to react for 30 minutes, and obtain white oxide Indium tin precursor;
[0045] 2) Wash the white indium tin oxide precursor prepared in step 1) three times with water and twice with ethanol, and then put it into a drying oven for drying at a temperature of 70°C. Grinding to obtain intermediate product B;
[0046] 3) Put the intermediate product B obtained in step 2) int...
