PRODUCTION OF FINE GRAIN PARTICLES.

摘要

A method for producing metal oxide particles having nano-sized grains, said method essentially consisting of: (a) preparing a solution containing one or more metal cations; (b) mixing the solution of step (a) with surfactant under conditions so that surfactant micelles are formed inside the solution to thereby form a micellar liquid; and (c) heating the micellar liquid formed in step (b) to form metal oxide, and the heating step is carried out at a temperature and for a period of time so that the surfactant is removed and thus formed Metal oxide particles that have a messy porous structure.
