Method for preparing superfine CaSiO3 conductive powder in micro-composite mode

The invention relates to a method for preparing superfine CaSiO3 conductive powder in a micro-composite mode. The method comprises the steps that alcohol serves as a reaction medium, at the temperature ranging from 10 DEG C to 100 DEG C, soluble calcium salt and orthosilicate ester are added according to the mole ratio of 1:1 so that CaSiO3 superfine powder can be prepared; the use amount of the alcohol is 1 to 10 times that of the soluble calcium salt according the mole ratio; ammonium hydroxide with the mass percent concentration smaller than or equal to 10% is gradually dripped in a silver nitrate solution with the concentration smaller than or equal to 6mol/L, so that a clear and transparent silver ammonia solution is obtained; at the temperature ranging from 10 DEG C to 100 DEG C, a mixed solution is prepared through the silver ammonia solution and an aldehyde solution according to the volume ratio of 1:1 and the CaSiO3 conductive powder is prepared through the mixed solution and the CaSiO3 superfine pow
