Difunctional pressure sensor alumina ceramic material and preparation method thereof
The invention provides a difunctional pressure sensor alumina ceramic material and a preparation method thereof, the material comprises the following components: nanoparticles with a molecular formula of CaCu3-xMxTi4O12, wherein 0 < x < = 1, and M is Ni, Zr, Co, and Sr; the glass-phase nano oxide particles with the molecular formula as A2O5, and the element A is Ta, Nb or V; single crystal diamond micro-powder; TiC; a microporous membrane polymer; a dimethyl formamide; and polyvinyl alcohol. The ceramic material is prepared, in which A2O5 glass phase nanoparticles in the outer shell are gradually increased along with the nanoparticles away from the CaCu3-xMxTi4O12 in the inner core, so that the dielectric constant is not reduced while the insulating property is improved, and the finally obtained capacitance pressure-sensitive sensor ceramic material has high dielectric constant, low dielectric loss and high insulating property.
本发明提供一种双功能压力传感器氧化铝陶瓷材料及其制备方法，所述材料包括以下成分：分子式为CaCu3‑xMxTi4O12的纳米颗粒，其中0＜x≤1，所述M为Ni、Zr、Co、Sr；分子式为A2O5的玻璃相纳米氧化物颗粒，所述元素A为Ta、Nb、V；单晶金刚石微粉；TiC；微孔膜聚合物；二甲基甲酰胺；聚乙烯醇。本发明通过制备得到随着远离内核CaCu3‑xMxTi4O12的纳米颗粒，外壳A2O5玻璃相纳米颗粒逐渐升高的陶瓷材料，进而保证了提高其绝缘性能的同时，不会降低其介电常数，进而使最终获得的电容压敏传感器陶瓷材料具有高介电常数、低介电损耗的同时，具有高绝缘性能。
