LiGaSiO4 microwave dielectric ceramic material with excessive lithium element and preparation method of LiGaSiO4 microwave dielectric ceramic material
The invention discloses a LiGaSiO4 microwave dielectric ceramic material with excessive lithium element and a preparation method of the LiGaSiO4 microwave dielectric ceramic material, and belongs to the technical field of preparation of electronic information functional materials. The preparation method of the LiGaSiO4 microwave dielectric ceramic material with excessive lithium element comprises the following steps: weighing Li2CO3, Ga2O3 and SiO2 according to the composition of Li1 + xGaSiO4 (x is more than or equal to 0 and less than or equal to 0.08), grinding and roasting to obtain prefabricated powder; and adding a binder into the prefabricated powder, granulating, carrying out compression molding, and sintering to obtain the LiGaSiO4 microwave dielectric ceramic material. The LiGaSiO4 microwave dielectric ceramic material with excessive Li is obtained by using a non-stoichiometric method, the crystal structure defect caused by Li volatilization in the high-temperature sintering process is relieved, the density of the ceramic is improved, and the LiGaSiO4 microwave dielectric ceramic material is more suitable for being used as microwave dielectric ceramic.
本发明公开了一种锂元素过量的LiGaSiO4微波介质陶瓷材料及其制备方法，属于电子信息功能材料制备技术领域。所述锂元素过量的LiGaSiO4微波介质陶瓷材料的制备方法包括如下步骤：按照Li1+xGaSiO4(0≤x≤0.08)的组成称取Li2CO3，Ga2O3和SiO2，粉磨，焙烧，得到预制粉末；在预制粉末中添加粘结剂造粒，压制成型，烧结，得到所述LiGaSiO4微波介质陶瓷材料。本发明运用非化学计量方法获得了一种Li过量的LiGaSiO4微波介质陶瓷材料，缓解了高温烧结过程Li挥发导致的晶体结构缺陷，提升了陶瓷致密度，更适合被用做微波介质陶瓷。
