Accession number: 081511196522 Title: Effects of gel pre-carbonization on Ca0.4Sr0.6Bi4 Ti4O15 nanocrystalline powder Authors: Fan, Suhua; Feng, Bokai; Wang, Peiji; Zhang, Fengqing; Zhang, Wei; Ma, Jianping Author affiliation: School of Material Science and Engineering, Shandong Jianzhu University, Jinan 250101, China Serial title: Kuei Suan Jen Hsueh Pao/ Journal of the Chinese Ceramic Society Abbreviated serial title: Kuei Suan Jen Hsueh Pao Volume: v 36 Issue: n 3 Issue date: March 2008 Publication year: 2008 Pages: p 311-314 Language: English ISSN: 0454-5648 CODEN: KSYHA5 Document type: Journal article (JA) Publisher: Chinese Ceramic Society, Beijing, 100831, China Abstract: Calcium strontium bismuth titanium (Ca0.4Sr0.6Bi4 Ti4O15) nanocrystalline powder with small particle size and good dispersion was prepared via the gel pre-carbonization sol-gel method. The temperature for gel pre-carbonization was determined by differential scanning calorimetry-thermal gravimetric analysis. The effects of pre-carbonization of gel on the properties such as the phase structure, microstructure and dispersion of the Ca0.4Sr0.6Bi4 Ti4O15 nanocrystalline powder were studied by X-ray diffraction and scanning electron microscope, respectively, and the pre-carbonization mechanism was also analyzed. Experimental results show that, after gel pre-carbonization at 300°C, the dispersion of the Ca0.4Sr0.6Bi4 Ti4O15 nanocrystalline powder improved, the particle size decreased, and the homogeneity of the powder improved. The phase structure was not influenced. The particle size with gel pre-carbonization was about 100 nm; however, the particle size without gel pre-carbonization was in the range of 100 nm-1μm. The mechanism is that, after the pre-carbonizing treatment, the precursor powder is modified and coated with carbon powder, which reduces grain agglomeration effectively.
