ZINC OXIDE POWDER AND PROCESS FOR MANUFACTURING SAME

摘要

The present invention provides a zinc oxide powder that enables a high degree of orientation, and highly uniform dispersion of an additive substance, to be simultaneously achieved in a green body or a sintered body. The zinc oxide powder of the present invention comprises a plurality of plate-like zinc oxide particles and has a volume-based D50 average particle diameter of 1 to 5 μm and a specific surface area of 1 to 5 m2/g. The zinc oxide powder has a degree of orientation of the (002) plane of 40% or greater when two-dimensionally arrayed into a monolayer on a substrate.
