example 1

[0019] Mix 100g of stannous oxalate and 8.1g of antimony trioxide, and thermally decompose it at 500°C for 40 minutes. After the thermally decomposed primary product is fully mixed, it is oxidized and roasted at 1100°C for 40 minutes to obtain light blue nano antimony-doped tin oxide powder. . The product is analyzed by electron microscope as a spherical powder with uniform particle size, and its XRD pattern is consistent with the standard pattern of tin dioxide. The primary particle size is 100% less than 100 nanometers according to the particle size analyzer. The nano-antimony-doped tin oxide has different resistivity.

example 2

[0021] 98g of stannous oxalate and 2g of antimony oxalate were mixed uniformly and thermally decomposed at 350°C for 60 minutes. The primary product after thermal decomposition was fully stirred and then oxidized and roasted at 950°C for 80 minutes to obtain light blue nano antimony-doped tin oxide. The product is analyzed by electron microscope as a spherical powder with uniform particle size, and its XRD pattern is consistent with the standard pattern of tin dioxide. The primary particle size is 100% less than 100 nanometers according to the particle size analyzer. The nano-antimony-doped tin oxide has different resistivity.

example 3

[0023] Mix 60g of stannous oxalate and 40g of antimony oxalate, and heat it at 700°C for 30 minutes to decompose it. The primary product after the heat decomposition is fully stirred and then oxidized and roasted at 1300°C for 25 minutes to obtain light blue nano antimony-doped tin oxide. The product is analyzed by electron microscope as a spherical powder with uniform particle size, and its XRD pattern is consistent with the standard pattern of tin dioxide. The primary particle size is 100% less than 100 nanometers according to the particle size analyzer. The nano-antimony-doped tin oxide has different resistivity.

Abstract

The invention relates to a method for manufacturing nano antimony doped tin oxide, which comprises the following steps of: performing complete thermal decomposition on a mixture of organic precursor tinoxalate of a tin and an antimonial substance at 250 to 800 DEG C; oxidizing and baking the rough product of the antimony doped tin oxide after the thermal decomposition at 800 to 1,500 DEG C for 15 to 90 minutes after completely and uniformly stirring the rough product to obtain the blue nano antimony doped tin oxide. The method avoids toxic hazardous chemical, such as chlorine and nitric acid, and a combustible and explosive organic solvent, so no pollutant is discharged in the whole production process. The method has the advantages of simple process and equipment, safe and environmentally-friendly production process and low production cost, and creates conditions for the industrial production with safety and low cost.

Description

Technical field [0001] The invention relates to a production method of nano antimony-doped tin oxide. Background technique [0002] Nano-antimony-doped tin oxide (ATO) is an N-type semiconductor material. Nano-antimony-doped tin oxide has good electrical conductivity, light color transparency, good weather resistance, stability and low infrared emissivity. It is a very Potential multifunctional conductive materials, mainly used in conductive coatings, antistatic coatings, conductive fibers and plastics, thermal insulation coatings, etc. Many researchers at home and abroad are committed to the research and development of this material. The preparation methods include sol-gel method, metal alkoxide hydrolysis method, chemical co-precipitation method, hydrothermal method and so on. Most of them use tin tetrachloride and antimony trichloride as raw materials, and use chlorine gas (chlorine gas is used in the production of tin tetrachloride), nitric acid and organic solvents suc...
