The results show that increasing the solids loading of slurry up to 45% allows minimizing deformation of green sheets during drying and sintering process effectively. When the content of monomers in shurry is 2%-4%, and the content of plasticizer in shurry is 3%-6%, green sheets with good strength and flexibility are obtained. The microstructures and the electric characteristics of PTCR chip thermistors were investigated. A five-layer chip PTCR thermistor with room resistance of 0.8Ω, temperature coefficient of resistance of 13.40%/℃, and ratio of maximum to minimum of resistance larger than 10^5 is successfully fabricated.
