| abstract |
The object of this invention is to provide columnar zinc oxide particles that are free from breaking or collapsing of a form when they are incorporated into, and mixed with, a resin and that can impart sufficient thermal conductivity or electrical conductivity. n This invention provides zinc oxide particles represented by the following formula (1), n n Z n M n+ x O 1+nx/2 · aH 2 O (1) n nwherein M n+ is a trivalent or tetravalent metal, x and "a" satisfy 0.002<x<0.05 and 0≤a<0.5, respectively, and having a columnar particle content of 80 % or more. |
