Ceramic dielectric material as well as preparation method and application thereof
The invention belongs to the technical field of ceramic materials, and particularly relates to a ceramic dielectric material and a preparation method and application thereof. The ceramic dielectric material provided by the invention comprises the following components in parts by mass: 100 parts of a base material, 1.65-8.5 parts of a modifier and 7-9 parts of a sintering aid, the base material is Sr1-xLa2x/3Zr1-yTiyO3, x is more than or equal to 0 and less than or equal to 0.06, and y is more than or equal to 0.05 and less than or equal to 0.10. The sintering aid has a relatively low melting point, the sintering aid forms a liquid phase in the sintering process, and the liquid phase can well wet ceramic powder particles, so that the sintering temperature is reduced, and low-temperature sintering is realized; strontium zirconate with high reduction resistance is subjected to A-site and B-site substitution, and a zirconium-titanium-strontium-lanthanum compound which keeps high reduction resistance and is more excellent in electrical property is generated and serves as a base material. The ceramic dielectric material disclosed by the invention has relatively low sintering temperature and good reduction resistance.
本发明属于陶瓷材料技术领域，具体涉及一种陶瓷介质材料及其制备方法和应用。本发明提供的陶瓷介质材料，包括以下质量份数的组分：100份基料，1.65～8.5份改性剂，7～9份烧结助剂；所述基料为Sr1‑xLa2x/3Zr1‑yTiyO3，其中0≤x≤0.06，0.05≤y≤0.10。烧结助剂具有较低的熔点，在烧结过程中烧结助剂形成液相，该液相能够很好地润湿陶瓷粉粒，从而降低烧结温度实现低温烧结；本发明对具有较强抗还原性的锆酸锶进行A、B位替代，生成保持较强抗还原性，且电性能更加优异的锆钛锶镧化合物作为基料。本发明的陶瓷介质材料具有较低的烧结温度和良好的抗还原性。
