摘要：
Provided are methods of manufacturing an oriented ceramics containing sodium niobate and a raw material thereof. Specifically, provided is a sodium niobate powder, including cuboidal sodium niobate particles having an average side length of 0.1 μm or more to 100 μm or less, at least one face of the cuboid including a (100) plane in pseudo-cubic notation, in which the sodium niobate powder has a perovskite single-phase structure.
