The effects of firing temperatures and barium content on phase formation, microstructure and dielectric properties of lead barium titanate ceramics prepared via the combustion technique

Phase Evolution, Microstructure and Dielectric Properties of CaCu3Ti4O12Ceramics Fabricated by Combustion Technique

“…The reaction can occur easily in a liquid system because the diffusion coefficient is higher than in a solid medium [17][18]. The obtained ceramics have a high density and excellent electrical properties with a low firing temperature and a short soaking time [15][16][17][18]. Furthermore, the preparation and characterization of CaCu 3 Ti 4 O 12 (CCTO) ceramics, using the combustion technique, have not been reported in the literature.…”

“…Our recent work has successfully fabricated ferroelectric ceramics using the combustion technique [15][16][17][18]. This technique involves a self-sustained reaction between the reactive materials and the fuel (e.g., urea and glycine) which supplies a liquid medium at the start of the reaction.…”

The Influence of Firing Temperatures on the Crystal Structure, Microstructure and Dielectric Properties of 0.79Bi0.5Na0.5TiO3-0.18Bi0.5K0.5TiO3-0.03BiFeO3Ceramics Prepared via the Combustion Technique

“…Recently, our previous works have successfully fabricated various high quality oxides ceramics such as: (Ba 1-x Sr x )(Zr x Ti 1-x )O 3 [12], Ba(Ti 1-x Zr x )O 3 [13], (Pb 1-x Ba x TiO 3 ) [14], 0.8Bi 0.5 Na 0.5 TiO 3-0.2Bi 0.5 K 0.5 TiO 3 [15], (Pb 0.90 Ba 0.10 )ZrO 3 [16] and Ba(Sn 0.1 Ti 0.9 )O 3 [17] by the combustion technique. The advantages of this technique include: inexpensive precursors, a simple preparation process, and resulting good electrical properties with a low firing temperature and a short dwell time [12][13][14][15][16][17]. Moreover, from the survey of literature, BNKFT ceramics, prepared by the combustion method, have not been studied.…”

Structural, microstructure and electrical properties of La2O3-doped Bi0.5(Na0.68K0.22Li0.1)0.5TiO3 lead-free piezoelectric ceramics synthesized by the combustion technique

“…Recently, the combustion technique has become an attractive technique to prepare ferroelectric materials because it is uncomplicated and economical [17][18][19][20][21]. This technique involves a self-sustained reaction between the reactive materials and the fuel (e.g., urea and glycine) which supplies a liquid medium at the start of the reaction.…”
