Synthesis, formation and characterization of ZnTiO3 ceramics

Sintering of mechanically activated Zno-TiO2 powders

“…12). Unfortunately, neither of these attempts to calculate the sintering phenomenon is close to the values obtained by other authors [12].…”

Densification rate and phase structure changes during sintering of zinc titanate ceramics

“…Zn 2 Ti 3 O 8 was first determined by Yamaguchi et al [6] as a low temperature form of ZnTiO 3 having a defect cubic spinel structure with ordered cation vacancies leading to degradation of the space group symmetry from Fd3m to P4 3 32 [7,8]. Taking into account the binary phase diagram for ZnO-TiO 2 [9] and literature data [3][4][5][6][7] the phase transitions in this system, for the ZnO:TiO 2 = 1:1 powder ratio are:…”

“…Much work has been devoted to the synthesis of ZnTiO 3 powder [3,4]. Dopants have been added to reduce the sintering temperature, but practical applications are partly restricted due to unstable dielectric properties originating from complex phase transitions [5].…”

Synthesis, characterization and optical properties of Zn1−xTixO nanoparticles prepared via a high-energy ball milling technique

“…In the first approach, ZnO nanoparticles can be prepared by chemical-based or solution-based methods such as sol-gel [6], precipitation [7] and a hydrothermal method [8]. In the second approach, ZnO nanoparticles can be prepared by mechanical milling techniques such as conventional ball milling [9] and high-energy ball milling [2]. All techniques above aim to reduce the crystallite and particle size and to produce ZnO particles with a narrow size distribution and regular particle shape.…”
