Abstract
The invention discloses a method for preparing a composite conductive filler by using fine coal gasification slag and the prepared composite conductive filler, and the method comprises the following steps: (1) roasting the fine coal gasification slag to remove carbon, carrying out hydrochloric acid dissolution treatment, and carrying out solid-liquid separation, washing and drying to obtain porous siliceous microbeads generated by the fine coal gasification slag; (2) putting the porous siliceous microbeads prepared in the step (1) into distilled water, stirring to form a suspension, then continuously stirring, and gradually adding a multi-ion mixed solution of SnCl4.H2O doped with SbCl3 into the suspension according to the addition amount that the mass of a precipitation product generated by hydrolysis of chlorine salt of Sn and Sb reaches 5-30% of the mass of the porous siliceous microbeads; and (3) after the mixed solution is added, continuously stirring to enable the hydrolysis reaction to be sufficient, then carrying out solid-liquid separation on the suspension, washing to remove Cl ions in a solid phase, drying and calcining to obtain the product. The prepared composite conductive powder is light in color and low in cost, can be widely used as conductive filler, and has dual significance in resources and environments.
