摘要：
The present invention provides ceramic compositions for preparing multi-layer capacitors, having high dielectric constants between about 4900 and 5400, dissipation factors below about 2.0%, high insulation resistance capacitance products and stable temperature coefficient characteristics, by a process of mixing a major ceramic component with one or more precipitated dopant components. By controlling the conditions of the system, precipitated dopant particles are charged oppositely to major ceramic component particles and are thus associated with the major ceramic component particles.
