摘要: Dielectric materials comprising nanocrystalline or nanoparticulate metal oxides or metal carbonates having enhanced dielectric constant values are provided. Specifically, the dielectric materials exhibit high dielectric constant values at low frequencies approaching the DC limit. The dielectric materials also exhibit low dielectric loss factors and high voltage breakdown limits making them well suited for use in capacitors, particularly high energy density capacitors.
