| Abstract: | Barium titanate ceramics based on barium carbonate and titanium dioxide is fabricated by wide-band laser sintering technology. Barium titanate ceramics is characterized by means of XRD and TG-DSC.The experimental results indicate that tetragonal barium titanate ceramics is synthesized by wide-band laser sintering,and its content is up to 91.5% of total.The Curie temperature is promoted from 120 ℃ to 125.9 ℃. |
