- Abstract
BaTiO3 powders were synthesized by microwave micro-zone heating technology with BaCO3 and TiO2 as raw materials, and SiC as good microwave conductors. The raw materials were grinded by ball milling, refined by sand milling and uniformly mixed with SiC microspheres. The synthesis temperature and qualitative analysis were determined by XRD. Raman and FT-TR. morphology was characterized by SEM. particle size was analyzed by PSD. and specific surface area was calculated by BET. The results show that tetragonal BaTiO3 powders with a particle size of 400 nm and uniform particle size distribution were prepared with microwave solid-state method by introducing microwave good conductor SiC into microwave micro-zone heating. Compared with traditional solid-state method, the particle size was smaller and the dispersivity was better. Tt provided a new idea for the microwave solid phase synthesis of barium titanate powder.
