ULTRAFINE ZINC OXIDE PARTICLE AND PROCESS FOR PRODUCTION THEREOF

摘要

The object of the present invention is to provide an ultrafine zinc oxide having a sufficient visible light transmittance in addition to an infrared ray shielding ability and conductivity, and also to provide a production method thereof. The ultrafine zinc oxide contains an element having a valence number of 3 or more, bears a metal compound on the surface, and has an average primary particle diameter of 0.1 µm or smaller.
