In the last two decades, structure and properties of Ruddlesden-Popper phase (RP) A 2 BO 4 oxides with K 2 NiF 4 structure, have been widely investigated. But to the best of our knowledge, no review article is available in the literature on recent studies on these oxides. Therefore, in this article, recent studies on structure, electrical, dielectric, and optical properties of these oxides have been reviewed. Special attention is put on to highlight the effect of doping and oxygen stoichiometry on the structure and properties of these oxides. Further, important applications of these oxides have also been mentioned in this article.

“…A large number of papers, both on the subject of analysis of the activation temperature in sintering and inelastic deformation of materials [139,140] and on that of the analysis of solidphase reaction mechanisms [141][142][143][144][145][146][147][148][149][150][151], show that all these solid-phase processes start in the systems only after the nonautonomous phase has transitioned to a liquid-like state, i.e., they are liquid-phase reactions in a sense, as stated in [75,78]. As another example, we can compare the findings from the study of Ruddlesden-Popper phase formation kinetics from different reagents [151][152][153][154][155][156][157][158][159][160][161][162][163][164][165][166][167][168] with data on the values of some temperature transformations in the Ln 2 O 3 -SrO-Al 2 O 3 system [169][170][171][172][173], in which the compounds are formed that are promising for the production of functional and structural high-temperature materials [174][175][176][177]…”

5Ti0.5O4. -Sr2Mn0.5Ti0.5O4 is prepared by sol-gel combustion of a mixture of Ti(O-iPr) 4, Sr(NO3)2, Mn(HCOO)2, and citric acid as well as diammonium citrate which shows a rapid volume expansion after evaporation at 430 C before being ignited and sintered (1. 943 K, 6 h, 2. 1323 K or 1573 K). Samples sintered at 1573 K show a pycnometric density of 98.2% of the X-ray density, a 100% phase purity, and a reduced pore size and pore amount compared with that sintered at 1323 K. The compound crystallizes in the tetragonal space group I4/mmm (powder XRD) and shows no oxygen vacancies. The oxidation states of Mn and Ti are +4 and the substitution of Ti 4+ for Mn 4+ does not affect the distortion of the (Mn,Ti)O6 and SrO9 polyhedra. The dielectric constant of the ceramic samples shows no frequency dependence. The dielectric properties are caused by the regular coordination polyhedra SrO 9 and the lack of charge ordering which leads to significant permittivity. Increase of the dielectric constant at temperatures >453 K is mainly caused by the grain boundary processes explained in terms of the Maxwell-Wagner polarization model. -(CHUPAKHINA*, T.
