Its main applications include multilayer capacitors, sensors, actuators, optoelectronic devices, field effect transistors and thermistors. In this paper, BaTiO3 ceramics with high density and excellent dielectric properties were prepared by low-temperature cold sintering process. The effects of flux type, cold sintering process (sintering temperature, sintering time, uniaxial pressure) and annealing method (traditional annealing and microwave annealing) on ceramic structure, microstructure and properties were explored. The effects of powder activation process (acetic acid concentration, activation time and activation temperature) on the cold Sintering Densification of ceramic samples were studied. According to MLCC preparation process, multilayer BaTiO3 ceramics were prepared by cold sintering process. By characterizing and analyzing the density, phase, microstructure and dielectric properties of the samples, the following conclusions are drawn:
