Medium dielectric constant microwave dielectric ceramic material and preparation method thereof
The invention discloses a medium-dielectric-constant microwave dielectric ceramic and a preparation method thereof, and belongs to the technical field of electronic functional ceramics. The expression of the material is (1-x) MnTiTa2O8-xTiO2, wherein x is equal to 0 to 0.2. The preparation method of the material comprises the following steps: proportioning the raw materials MnO, TiO2 and Ta2O5 according to a certain proportion, carrying out ball milling, drying and sieving, pre-sintering, carrying out secondary ball milling, granulating, carrying out compression molding to obtain a cylindrical sample, sintering the cylindrical sample in a temperature range of 1200-1350 DEG C, and carrying out heat preservation for 3.5-4.5 h to finally prepare the (1-x) MnTiTa2O8-xTiO2 (x = 0-0.2) ceramic material. The novel ceramic material provided by the invention has the characteristics of easiness in preparation, medium dielectric constant, low loss, good temperature stability and the like, can be used as a key material of a dielectric resonator and a ceramic filter, and lays a good foundation for theoretical research of enriching a titanium tantalate-based microwave dielectric ceramic system.
本发明公开了一种中介电常数微波介质陶瓷及其制备方法，属于电子功能陶瓷技术领域。材料的表达式为(1‑x)MnTiTa2O8‑xTiO2，其中x＝0～0.2。该材料制备方法是先将原料MnO、TiO2、Ta2O5按一定比例配料，经球磨、烘干过筛、预烧、二次球磨、造粒后压制成型为圆柱试样，并将其在1200℃～1350℃的温度范围内烧结保温3.5—4.5h，最终制备出(1‑x)MnTiTa2O8‑xTiO2(x＝0～0.2)陶瓷材料。本发明提供的一种新型陶瓷材料具有易制备、中等介电常数、低损耗、温度稳定性良好等特性，可作为介质谐振器、陶瓷滤波器的关键材料，并为丰富钽酸钛基微波介质陶瓷体系的理论研究奠定良好的基础。
