Abstract

The heterogeneous conglomeration method, chemical precipitation method and Hydroxy combination theory are adopted in the paper through detailed theoretical analysis and contrast experiments. Tourmaline powder surface is completely covered with ZnO by 1.2:1 mass ratio of ZnO to tourmaline powder. Submicron-nanometer powder is achieved due to 78.71 mean particle diameter, the electrical resistivity of composite powder is decreased to 7.45Ω.cm. Improvement of conductive performance extends the application of tourmaline in the field of environmental purification.
