Abstract
A product and process are disclosed that relate to electroconductive powders based on tantalum niobium, or phosphorus or any combination thereof doped tin oxide and coatings containing such powders. These powders can be used for making transparent coated films that are conductive and have desirable properties for a number of end uses. Some important end uses are in static dissipative fiber and films, coatings for recyclable containers, materials involved in packaging, where the presence of certain heavy metals is undesirable, transparent conductive coatings, among other uses.
