摘要：
The present invention relates to a method for preparing an iron oxide-based gloss and, more specifically, to a method for preparing an iron oxide-based black glossy pigment with high yield using iron sulfate as a starting material through thermal synthesis without sintering, wherein the method comprises the steps of: preparing an iron sulfate dilution liquid forming a suspension of flake substrates titrating the substrate suspension with an aqueous inorganic salt solution and mixing the iron sulfate dilution liquid therewith, thereby coating an oxide layer on surfaces of the flake substrates.
