Collections of composite particles comprise inorganic particles and another composition, such as a polymer and/or a coating composition. In some embodiments, the composite particles have small average particle sizes, such as no more than about 10 microns or no more than about 2.5 microns. The composite particles can have selected particle architectures. The inorganic particles can have compositions selected for particular properties. The composite particles can be effective for printing applications, for the formation of optical coatings, and other desirable applications. L'invention porte sur des collections de particules composites contenant des particules inorganiques et une autre composition, tel un polymère et/ou une composition de revêtement. Dans certains modes de réalisation, les particules composites présentent des granulométries moyennes petites, par exemple inférieures ou égales à 10 microns environ ou inférieures ou égales à 2,5 microns environ. Ces particules composites présentent des architectures particulaires sélectionnées. Les particules inorganiques possèdent des compositions sélectionnées selon des propriétés spécifiques. Lesdites compositions particulaires sont efficaces dans des applications d'impression, dans la formation de revêtements optiques, et dans d'autres applications recherchées.
