CONDUCTIVITY ORIENTATED ZINC OXIDE FLAKE AND ITS MANUFACTURING PROCESS

摘要

PROBLEM TO BE SOLVED: To establish a in a conductivity orientated zinc oxide flake that display an excellent performance as a conductive component to add to an anti- static additive and an anti-static paint, and its manufacturing process. SOLUTION: A conductivity orientational zinc oxide flake having an index determined according to the following formula (1) of 40 or more and containing a trivalent metal oxide in 1×10-4 to 2×10-1 mol per mol of zinc oxide in metal conversion and its manufacturing method is disclosed. Orientational index = [34.56 deg./(31.88 deg.+34.56 deg.+36.36 deg.)×100 (Each numerical value in the formula represents a strength at 2θangle in X-ray diffraction).
