Improved microwave dielectric ceramic powder and preparation method and application thereof
The invention discloses improved microwave dielectric ceramic powder and a preparation method and application thereof. The microwave dielectric ceramic powder comprises ceramic powder prepared from the following raw materials in parts by weight: 30-40 parts of calcium carbonate, 25-30 parts of titanium dioxide, 25-35 parts of samarium oxide, 5-15 parts of aluminum oxide, 0.5-2 parts of cerium oxide and 0.01-0.5 part of niobium oxide. The improved microwave dielectric ceramic powder prepared by the method is a microwave dielectric material with high QxFo [ceramic quality factor] value and low loss of dielectric constant 43, the electrical performance of microwave components such as a cavity filter can be significantly improved, especially the insertion loss of the filter is reduced, and a more stable temperature coefficient is obtained so that the influence on the filter due to use environment factors in actual use is reduced.
本发明公开了一种改良微波介质陶瓷粉及其制备方法、及其应用，微波介质陶瓷发包括以下原料按照重量份制备而成的陶瓷粉末：碳酸钙30‑40份、二氧化钛25‑30份、氧化钐25‑35份、氧化铝5‑15份、氧化铈0.5‑2份、以及氧化铌0.01‑0.5份。本发明制备的改良微波介质陶瓷粉为介电常数43的高QxFo[陶瓷品质因素]值、低损耗的微波介质材料，能显著改善微波元器件如腔体滤波器的电性能，特别是降低滤波器的插入损耗，获得更稳定的温度系数，以减少滤波器在实际使用中因使用环境因素对滤波器所造成的影响。
