ABSTRACT:
The disclosure relates broadly to a new class or type of electroconductive powders (ECP), designated as Polytype ECP (PECP), comprising intimate mixtures of several types of ECP powders. PECP mixtures possess a lower electrical resistivity, or a higher electroconductivity, than would be expected from the weighted average of the component ECP powders. PECP are multi-component and may contain many different types of ECP. ECP components of the PECP can be selected from at least one member of the group consisting of crystallites of tin oxide containing antimony in solid solution, crystallites of antimony-containing tin oxide with uniformly distributed amorphous silica, two dimensional networks of crystallites of antimony-containing tin oxide in a unique association with amorphous silica or silica-containing material, filler materials, metal coated powders, conventional ECP materials such as carbon, aluminum powder, among others.
