[0018] Example 1:
[0019] The preparation of composite conductive powder with soft kaolinite mineral from a certain place in Guangxi as the matrix includes the following steps:
[0020] (1) Mix 40g of kaolin powder and 160g of deionized water into a solution with a solid content of 20%, add polyethylene glycol as a dispersant, and place it in an electric thermostatic water bath at 50°C and fully stir to make the mineral particles evenly dispersed. Make a suspension slurry.
[0021] (2) Prepare SnCl with 1.5mol / L hydrochloric acid 4 ·5H 2 O acid solution, with a concentration of 0.1 mol / L, dissolve completely on a magnetic stirrer, with a molar doping ratio of 92:8 and weigh the corresponding SbCl 3 Dissolve in the above acid solution and continue to stir to mix evenly.
[0022] (3) Ammonia water with a concentration of 20% of acidic mixed solution and lye precipitant is dropped into a reactor containing a uniformly dispersed kaolin suspension and kept stirring through a liquid di...
