| 摘要 |
THE INVENTION RELATES TO AN ALKALINE-EARTH METAL CARBONATE POWDER COMPRISING A CORE CONSISTING ESSENTIALLY OF AT LEAST ONE ALKALINE-EARTH METAL CARBONATE AND A SHELL CONSISTING ESSENTIALLY OF AT LEAST ONE GROUP IV TRANSITION METAL COMPOUND, TO THE METHOD FOR MANUFACTURING THE SAME AND TO AN IMPROVED METHOD FOR PREPARING HIGHLY CRYSTALLINE ALKALINE-EARTH METAL CONTAINING MIXED OXIDE POWDER. THE HIGHLY CRYSTALLINE MIXED OXIDES OBTAINED BY MEANS OF THE PROCESS ACCORDING TO THE INVENTION ARE USED AS STARTING MATERIAL FOR HIGH-PERFORMANCE DIELECTRIC, ESPECIALLY MULTI-LAYER CAPACITORS, AND FOR HIGH PERFORMANCE DIELECTRICS. |
