ZnO-based low-voltage high-nonlinearity voltage-sensitive ceramic co-fired with pure silver inner electrode and preparation method thereof
The invention discloses a ZnO-based low-voltage high-nonlinearity voltage-sensitive ceramic material which is high in nonlinearity and can be co-fired with a pure silver inner electrode and a preparation method thereof. The preparation method comprises the following steps: 1) keeping the temperature at 750 DEG C for 2 hours according to a molar ratio of Bi2O3 to Sb2O3 of 13.8, and synthesizing a Bi-Sb-O additive in advance; 2) selecting ZnO, Bi2O3, Co2O3, MnO2, Sb2O3 and Bi-Sb-O as raw materials, weighing corresponding raw materials according to a formula of 98 mol% ZnO (99.0%) + 0.5 mol% Bi2O3 (99%) + 1 mol% MnO2 (98.8%) + 0.5 mol% Co2O3 (99.0%) + x wt% Bi-Sb-O (0 < x < = 5); and (3) molding the uniformly ball-milled and mixed mixture by using a solid-phase sintering method, removing plastic, and sintering at the temperature of 900 DEG C for 2-5 hours to obtain the ZnO-based voltage-sensitive ceramic material. The comprehensive performance of the ZnO-based piezoresistor material obtained by the invention is as follows: the voltage-sensitive field intensity is as low as 235V/mm, the nonlinear coefficient alpha is as high as 53.0, and the leakage current IL is as low as 0.005 mu A.In addition, the preparation method has the advantages of being simple in process, low in energy consumption, environmentally friendly, capable of being co-fired with a pure silver inner electrode andthe like.
