  • Patent number: 8450231
    Abstract: This invention relates to a method for manufacturing silicon-containing particles characterized by preparing a uniform phase comprising a curable composition that includes a silicon-containing compound having in one molecule one or more reactive functional groups per 50 silicon atoms and an oil that does not participate in curing of the composition, then curing the composition, and causing phase separation from the oil for obtaining the silicon-containing particles; and to silicon-containing particles obtained by the above method. The method provides silicon-containing particles of an extremely small diameter in a simple process without the use of surfactants. And the silicon-containing particles possess excellent dispersibility in oil and a high degree of ceramification by baking.
