一种新型高介电复合材料的低温制备方法
摘要：
本发明涉及一种新型高介电复合材料的低温制备方法，本发明中利用多孔陶瓷片在金属盐浸渍液浸渍后，进行真空处理，将真空处理后的多孔陶瓷片埋入陶瓷粉体中干燥得到金属盐/陶瓷复合前驱体，在300-700℃温度下对金属盐/陶瓷复合前驱体进行煅烧得到金属氧化物/陶瓷复合前驱体，然后在300-700℃温度下同时通入还原性气体进行煅烧还原得到多孔金属/陶瓷复合材料。本发明中多孔陶瓷基体中均匀地负载具有不同微观形貌的导电相，添加极少量的导电相便可获得远高于基体的介电常数。
摘要（英）：

The invention relates to a low-temperature preparation method of a novel highly-dielectric composite material. The low-temperature preparation method comprises steps as follows: a porous ceramic plate after being impregnated in a metal salt impregnation liquid is subjected to vacuum processing, the porous ceramic plate after vacuum processing is embedded into ceramic powder for drying, a metal salt/ceramic composite precursor is obtained and is calcined at the temperature of 300-700 DEG C, a metallic oxide/ceramic composite precursor is obtained, then reducing gas is introduced simultaneously at the temperature of 300-700 DEG C for calcination and reduction, and the porous metal/ceramic composite material is obtained. The porous ceramic substrate is uniformly loaded with conductive phases with different microstructures, and the dielectric constant higher than that of the substrate can be acquired with addition of a minuscule amount of conductive phases.
