| Title: | Nanosized barium titanate powder by mechanical activation | Authors: | Xue, J. Wang, J. Wan, D. |
Issue Date: | 2000 | Citation: | Xue, J.,Wang, J.,Wan, D. (2000). Nanosized barium titanate powder by mechanical activation. Journal of the American Ceramic Society 83 (1) : 232-234. ScholarBank@NUS Repository. | Abstract: | Mechanical activation, without any additional heat treatment, is used to trigger the formation of a perovskite BaTiO3 phase in an oxide matrix that consists of BaO and TiO2 in a nitrogen atmosphere. The resulting BaTiO3 powder exhibits a well-established nanocrystalline structure, as indicated by phase analysis using X-ray diffractometry. A crystallite size of approx. 14 nm is calculated, based on the half-width of the BaTiO3 (110) peak, using the Scherrer equation, and an average particle size of 20-30 nm is observed using transmission electron microscopy for the activation-derived BaTiO3 powder. | Source Title: | Journal of the American Ceramic Society | URI: | http://scholarbank.nus.edu.sg/handle/10635/107141 | ISSN: | 00027820 |
