Low-temperature sintered low-dielectric-constant microwave ceramic material and preparation method thereof
The invention discloses a low-temperature sintered low-dielectric-constant microwave ceramic material and a preparation method thereof, and belongs to the technical field of information function materials. The low-temperature sintered low-dielectric-constant microwave ceramic material is prepared from the following raw material components in percentage by mass: 75 to 95 percent of 2MgO-2Al2O3-5SiO2, 1 to 8 percent of SiO2, 1 to 8 percent of Yb2O3 and 3 to 15 percent of Ca2 (OH) 2CO3; the preparation method comprises the following processes: burdening, pre-sintering and mixing, granulating and forming, degumming, sintering and the like. The sintering temperature of the microwave ceramic is regulated and controlled by adding the sintering aid and the active agent, meanwhile, the ceramic material has a low dielectric constant and a small temperature frequency drift coefficient, the preparation process is simple, the preparation cost is low, and the practicability is very high.
本发明公开了一种低温烧结低介电常数微波陶瓷材料及其制备方法，属于信息功能材料技术领域。所述低温烧结低介电常数微波陶瓷材料原料组分按质量百分比为：2MgO‑2Al2O3‑5SiO275‑95％，SiO21‑8％，Yb2O31‑8％，Ca2(OH)2CO33‑15％；所述制备方法包括配料、预烧混合、造粒成型、排胶、烧结等工艺；本发明通过添加烧结助剂和活性剂来调控微波陶瓷的烧结温度，同时使陶瓷材料具有低的介电常数、较小的温度频率漂移系数，制备工艺简单，制备成本低，具有很强的实用性。
