Embodiment 1
[0019] The preparation of composite conductive powder with soft kaolinite minerals in a certain place in Guangxi as the matrix includes the following steps:
[0020] (1) 40g of kaolin powder and 160g of deionized water are made into a solution with a solid content of 20%, adding polyethylene glycol as a dispersant, and fully stirring in an electric heating constant temperature water bath at 50°C to make the mineral particles disperse evenly, Made into suspension slurry.
[0021] (2) Prepare SnCl with 1.5mol / L hydrochloric acid 4 ·5H 2 O acid solution with a concentration of 0.1mol / L, placed on a magnetic stirrer to completely dissolve, and the molar doping ratio of 92:8 to weigh the corresponding SbCl 3 Dissolve in the above acid solution and continue stirring to mix evenly.
[0022] (3) Acidic mixed solution and lye precipitating agent concentration are 20% ammoniacal liquor, drip in the reactor that fills the evenly dispersed kaolin suspension and keep stirring by liquid ...
