Method for codoping TiO2 voltage-sensitive ceramic, codoped TiO2 piezoresistor and preparation method of TiO2 voltage-sensitive ceramic
The invention relates to a method for codoping TiO2 voltage-sensitive ceramic, a codoped TiO2 piezoresistor and a preparation method of the TiO2 voltage-sensitive ceramic, and belongs to the technical fields of electrical elements and material manufacturing of the electrical elements. The method comprises the following steps: firstly, adding Ge, GeO2, V2O5 and Y2O3 to TiO2 to obtain a mixture; carrying out wet-milling, drying, sieving and pelletizing the mixture, further sieving, and pressing powder into small disks; and heating the small disks, discharging glue, thermally sintering and cooling to a room temperature to prepare (Ge, GeO2, V2O5 and Y2O3) codoped TiO2 voltage-sensitive ceramic. The voltage-sensitive ceramic surface is processed, is subjected to silver electrode firing by an electrode, and then is encapsulated to obtain the (Ge, GeO2, V2O5 and Y2O3) codoped TiO2 piezoresistor. The performance of a TiO2-based voltage-sensitive ceramic resistor is improved.
