摘要:
Dielectric powder and thick-film paste compositions are formed having high dielectric constants, low loss tangents, and other desirable electrical and physical properties. Conductive powder and paste compositions are formed having desirable electrical and physical properties. The dielectric powder and thick-film paste compositions can be used in combination with the conductive powder and paste compositions to form capacitors and other fired-on-foil passive circuit components.
