Embodiment 1

[0021] Weigh Al(NO 3 ) 3 9H 2 O0.37 g, Zn(NO 3 ) 2 ·6H 2 O14.6 grams, 7.5 grams of glycine (combustion enhancer accounts for 50% of the total mass of zinc source and aluminum source). Put it in a mortar and grind it thoroughly until it becomes transparent. Pour it into a crucible, put it into an oven, set the temperature at 100°C, and dry it for 2 hours until the precursor is gelatinous. Then put the crucible into the muffle furnace, and set the calcination temperature to 700°C. After calcination for 2 hours, it was naturally cooled to room temperature to obtain light yellow ZAO nanopowder. The particle size of the product was about 40nm observed by transmission electron microscope.

Embodiment 2

[0023] Weigh Al(NO 3 ) 3 9H 2 O0.37 g, Zn(NO 3 ) 2 ·6H 2 O14.6 grams, 1.5 grams of glycine (combustion enhancer accounts for 10% of the total mass of zinc source and aluminum source). Put it in a mortar and grind it thoroughly until it becomes transparent. Pour it into a crucible, put it into an oven, set the temperature at 75°C, and dry it for 8 hours until the precursor is gelatinous. Then put the crucible into the muffle furnace, set the calcination temperature to 500°C, and after calcination for 3 hours, cool down to room temperature naturally to obtain light yellow ZAO nanopowder. The particle size of the product is about 25nm observed by transmission electron microscope.

Embodiment 3

[0025] Weigh Al(NO 3 ) 3 9H 2 O0.37 g, Zn(NO 3 ) 2 ·6H 2 O14.6 grams, 15.0 grams of glycine (combustion enhancer accounts for 100% of the total mass of zinc source and aluminum source). Put it in a mortar and grind it thoroughly until it becomes transparent. Pour it into a crucible, put it into an oven, set the temperature at 90°C, and dry it for 3 hours until the precursor is gelatinous. Then put the crucible into the muffle furnace, set the calcination temperature to 800°C, and after calcination for 1 hour, cool to room temperature naturally to obtain light yellow ZAO nanopowder. The particle size of the product is about 50nm observed by transmission electron microscope.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a preparation method of a light-colored conductive nano-powder material. Background technique [0002] Zinc oxide is a semiconductor optoelectronic material with a wide range of applications. Its band gap at room temperature is 3.37eV, and its exciton binding energy is as high as 60meV. Aluminum-doped zinc oxide (Zinc Aluminum Oxide, referred to as ZAO) is a replacement solid solution formed by zinc oxide and aluminum oxide. It not only has good ultraviolet absorption performance and high chemical stability, but also has light color, high visible light transmittance, and good conductivity. characteristics, can be widely used in antistatic coatings, rubber and plastics, etc., and can replace ITO (In 2 o 3 :Sn) material trends. [0003] At present, the research on nano-ZAO nanomaterials mainly focuses on the preparation of thin films and the research on rel...
