<p>This invention relates to the in-situ synthesis of multi-core electroconductive powders. The multi-core ECPs of the present invention are made using an in-situ synthesis method which eliminates the need for combining mixtures of various types of single-core ECPs in order to achieve the desired end-use product. The multi-core ECPs described herein exhibit very little coloration. They also exhibit low electrical resistivity and contain reduced amounts of antimony.</p>
