Dielectric ceramic material
A dielectric ceramic material includes the composite ceramic powder of BaTiO 3 and Ba 2 LiTa 5 O 15 , or BaTiO 3 and Ba 2 LiNb 5 O 15 that are based on the oxides of BaO, TiO 2 , Li 2 O and Ta 2 O 5 , or BaO, TiO 2 , Li 2 O and Nb 2 O5 as initial powder materials prepared subject to a respective predetermined percentage. This dielectric ceramic material simply uses simple binary oxides as initial powder materials that are easy to obtain and inexpensive, and that eliminate the complicated manufacturing process of synthesizing BaTiO 3 , Ba 2 LiTa 5 O 15 or Ba 2 LiNb 5 O 15 , making the whole process more simple and the manufacturing cost more cheaper and preventing the formation of other compounds.
