Dielectric ceramic material and preparation method thereof
The invention discloses a dielectric ceramic material and a preparation method thereof, and relates to the technical field of dielectric ceramic materials, and the technical key points are as follows: the dielectric ceramic material comprises barium titanate (BaTiO3) which accounts for 80-99 wt% of the weight of the finished dielectric ceramic material; the dielectric ceramic material also comprises a dopant, and the dopant accounts for 1-20wt% of the weight of the dielectric ceramic material finished product. The doping agent comprises silicon dioxide (SiO2), magnesium carbonate (MgCO3), manganous-manganic oxide (Mn3O4), barium titanate (BaCO3) and rare earth oxide D2O3; wherein D represents any one or more of yttrium (Y), holmium (Ho), ytterbium (Yb), gadolinium (Gd) and dysprosium (Dy); the invention provides a dielectric ceramic material which meets the EIAX7R standard and still has a high IR characteristic and a low dielectric loss factor (tan delta) in a high-temperature environment and a preparation method of the dielectric ceramic material.
本发明公开了一种介电陶瓷材料及其制备方法，涉及介电陶瓷材料技术领域，其技术要点：包括钛酸钡(BaTiO3)，所述钛酸钡占该介电陶瓷材料成品重量的80～99wt％；还包括掺杂剂，所述掺杂剂占该介电陶瓷材料成品重量的1～20wt％；所述掺杂剂包括二氧化硅(SiO2)、碳酸镁(MgCO3)、四氧化三锰(Mn3O4)、钛酸钡(BaCO3)以及稀土氧化物D2O3；其中D代表钇(Y)、钬(Ho)、镱(Yb)、钆(Gd)、镝(Dy)中的任意一种或多种；本发明提供了一种符合EIAX7R标准且在高温环境下仍具有高的IR特性与低的介质损失因数(tanδ)的介电陶瓷材料及其制备方法。
