ALKALINE-EARTH METAL CARBONATE CORE COATED WITH AT LEAST ONE GROUP IV TRANSITION METAL COMPOUND

摘要

The invention, one core and at least as a main component an alkaline earth metal carbonate at least one Group IV transition alkaline earth metal carbonate powder comprising a shell, composed mainly of metal compounds, their preparation, and highly crystalline alkaline-earth metal containing mixed oxide powder the present invention relates to an improved production method. Crystalline mixed oxides obtained by the anti-caking method according to the invention is a high-performance dielectric, especially as starting materials for the multi-layer capacitor and high-performance dielectric stay. ; Alkaline earth metal carbonates, transition metal of Group IV, a highly crystalline mixed oxide, high-performance dielectric, multilayer capacitors
