LTCC ceramic powder for high-frequency capacitor and preparation process of LTCC ceramic powder
The invention discloses LTCC ceramic powder for a high-frequency capacitor and a preparation process of the LTCC ceramic powder, and belongs to the field of LTCC ceramic powder. The preparation process of the LTCC ceramic powder for the high-frequency capacitor comprises the following steps: 1, preparing crystallizable calcium borosilicate glass powder (CBS); 2, preparing glass sintering aid powder (LBS); 3, preparing (Zn0.7Mg0.3) TiO3 ceramic powder (ZMT); and 4, preparing composite ceramic powder, wherein the prepared ZMT, CBS and LBS is mixed with purchased CT (CaTiO3); and carrying out ball milling on the powder, taking an organic solvent such as absolute ethyl alcohol as a ball milling medium, sieving and separating balls, drying the slurry, and carrying out dry milling and scattering to obtain the LTCC composite ceramic powder for the high-frequency capacitor. According to the LTCC ceramic powder for the high-frequency capacitor and the preparation process of the LTCC ceramic powder, domestication of low-loss capacitor ceramic powder under the high-frequency condition is achieved, and the LTCC ceramic powder can be used for preparing multilayer or single-layer ceramic capacitors and has important application in the fields of 5G communication, intelligent automobiles and the like.
本发明公开了高频电容器用LTCC瓷粉及其制备工艺，属于LTCC瓷粉领域，高频电容器用LTCC瓷粉及其制备工艺包括如下步骤：步骤1——制备可晶化钙硼硅玻璃粉(CBS)；步骤2——制备玻璃助烧剂粉末(LBS)；步骤3——制备(Zn0.7Mg0.3)TiO3陶瓷粉(ZMT)；步骤4——制备复合瓷粉：将制备的ZMT、CBS、LBS和采购的CT(CaTiO3)进行混合；对粉料进行球磨，并用有机溶剂如无水乙醇做球磨介质，过筛分离球子，烘干浆料，干磨打散，得到高频电容器用LTCC复合瓷粉。本发明公开的高频电容器用LTCC瓷粉及其制备工艺，实现了高频条件下的低损耗电容器瓷粉的国产化，可用于制备多层或单层陶瓷电容器，在5G通讯、智能汽车等领域有重要用途。
