High-Q-value borate microwave dielectric ceramic material as well as preparation method and application thereof
The invention provides a high-Q-value borate microwave dielectric ceramic material as well as a preparation method and application thereof. The chemical composition expression of the ceramic material is (Zn < 1-x > Mg < x >) < 2.99 > Li < 0.02 > (BO < 3 >) < 2 >, and x is equal to 0.01 to 0.1. The preparation method comprises the following steps: according to chemical composition requirements of the ceramic material, carrying out primary ball milling on a Zn source, a Mg source, a Li source and a B source to obtain preformed powder, carrying out drying, crushing, presintering and cooling processes on the preformed powder to obtain prefabricated powder, carrying out ball milling, secondary drying, granulation, secondary crushing and molding on the prefabricated powder to obtain a molded sample, and sintering the molded sample according to a sintering temperature curve to obtain the ceramic material. The ceramic material is obtained. The relative density of the (Zn1-xMgx) 2.99 Li0.02 (BO3) 2 ceramic material is up to 98% or above, and the (Zn1-xMgx) 2.99 Li0.02 (BO3) 2 ceramic material has the characteristics of high Q value and low dielectric constant, and can be applied to information communication materials.
本发明提供一种高Q值硼酸盐微波介质陶瓷材料、制备方法和应用。所述陶瓷材料的化学组成表达式为(Zn1‑xMgx)2.99Li0.02(BO3)2；x＝0.01～0.1。制备方法为：按照陶瓷材料的化学组成要求，将Zn源、Mg源、Li源和B源，进行第一次球磨得到预型粉，预型粉进行干燥、碾碎、预烧结及冷却工艺得到预制粉，预制粉进行球磨，二次干燥、造粒、二次碾碎和成型得到成型样，成型样按照烧结温度曲线进行烧结，得到陶瓷材料。本发明的(Zn1‑xMgx)2.99Li0.02(BO3)2陶瓷材料，相对致密度最高达到98％以上的致密化，具有高Q值和低介电常数的特点，可应用于在信息通讯材料中。
