Medium-dielectric-constant low-temperature sintering microwave dielectric ceramic material and preparation method thereof
The invention relates to a medium-dielectric-constant low-temperature sintering microwave dielectric ceramic material which comprises a main-phase ceramic material Ba5-xNb4O15-x and a sintering aid A, and x is more than or equal to 0 and less than or equal to 1.5; the sintering aid A accounts for 1-15 wt% of the mass fraction of the Ba < 5-x > Nb < 4 > O < 15-x >; the sintering aid A is one or more of ZBS glass and CuO and a compound of aRO-bAl2O3-cB2O3-dSiO2, or the sintering aid A is only the compound of aRO-bAl2O3-cB2O3-dSiO2, and R is at least one of Ba or Ca. According to the medium-dielectric-constant low-temperature sintering microwave dielectric ceramic material provided by the invention, the risk of cross-linking reaction between the medium-dielectric-constant low-temperature sintering microwave dielectric ceramic material and organic matters such as PVA (Polyvinyl Alcohol) and PVB (Polyvinyl Butyral) in a tape casting process is reduced by The comprehensive frequency temperature coefficient of the material is adjusted through a non-stoichiometric ratio, so that the risk of performance deterioration and difficult cooling caused by addition of the second-phase ceramic material is reduced.
本发明涉及一种中介电常数低温烧结微波介质陶瓷材料，包括：主相陶瓷材料Ba5‑xNb4O15‑x和烧结助剂A，其中0≤x≤1.5；烧结助剂A占Ba5‑xNb4O15‑x质量分数的1～15wt％；烧结助剂A为ZBS玻璃、CuO中的一种或多种以及aRO‑bAl2O3‑cB2O3‑dSiO2复合物，或仅为aRO‑bAl2O3‑cB2O3‑dSiO2复合物，其中R为Ba或Ca中的至少一种。本发明提供的中介电常数低温烧结微波介质陶瓷材料，通过复合物为助剂降低其在流延过程中与PVA、PVB等有机物发生交联反应风险；通过非化学计量比调整材料综合频率温度系数，降低添加第二相陶瓷材料导致性能恶化及降温困难的风险。
