Production of tailor-made particle size distributions of substantially spherical metal hydroxide/oxide particles comprising single or multiple hydroxides by hydrolysis of one or more metal alkoxide aerosols

摘要

The invention comprises high purity substantially spherical metal oxide particles having one or more predominant particle sizes formed from one or more metal alkoxides. In one embodiment there is disclosed multimodal particle size distributions of such substantially spherical metal hydroxide particles while a second embodiment describes the formation of such particles using more than one metal alkoxide to form either a mixed metal hydroxide particle or a layered particle comprising a core of a first metal hydroxide and at least one layer of an additional metal hydroxide.
