PROBLEM TO BE SOLVED : To provide an inexpensive and high-performance temperature coefficient-improved microwave dielectric material capable of approximating a temperature coefficient to zero and reducing a calcination temperature. SOLUTION : The microwave dielectric material is characterized by having BaLa2Ti3O10as a temperature improving agent incorporated to a ceramic dielectric composition. Further, the microwave dielectric material is characterized by having colemanite as a calcination temperature reducing agent incorporated into a ceramic dielectric composition. When selecting a homologous material of AxR4Ti3+xO12+3xfor a principal constituent (where A is an alkali earth metal element, R is a rare earth element, and the composition ratio X is within the range expressed by 0.5COPYRIGHT : (C)2008, JPO&INPIT |
