Temperature dependent tunability data and modelling in the paraelectric Ba0.7Sr0.3TiO3 solid solutions [PDF]
Processing and Application of Ceramics, 2009 The fi eld dependence of the dielectric constant (dc-tunability) as a function of temperature in (Ba,Sr)TiO3 ceramics was investigated. Dense and homogeneous BaxSr1-xTiO3 ceramics prepared by Pechini method show low losses, high dielectric constant of ...

Effects of the atmosphere and substrate on the crystallization of PLZT thin films
Materials Research, 2000 Lead lanthanum zirconate titanate [PLZT (9/65/35)] thin films were prepared by dip-coating on Si (100) or Si/Ti/Pt (100) substrates using a polymeric precursor solution and annealed at 650 °C for 3 h. Perovskite phase formation of the PLZT thin films and

Synthesis of (Bi,Pb)-2223 superconductor powder by pechini method
Revista Brasileira de Física Tecnológica Aplicada, 2018 In this paper, we present a detailed route of synthesis to produce ceramic superconductor Bi1,6Pb0,4Sr2Ca2Cu3Ox (Bi,Pb)-2223 powder by Pechini method. The obtained polymeric precursor solution was produced by using inexpensive chemical reagents, which showed a great stability for three weeks with high concentration of BPSCCO inorganic ions.

Nanostructuring Copper Tungstate Photoanodes: Performance Enhancement and Fundamental Limitations
Small Structures, Volume 7, Issue 3, March 2026.Nanostructuring of CuWO4 photoanodes yields a ~ tenfold photocurrent enhancement compared to dense films, reaching 0.6 mA cm−2 at 1.23 V versus reversible hydrogen electrode, among the best values reported for this material. Yet, performance remains far below the theoretical limit due to severe bulk recombination and poor electron transport ...

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.Abstract This article reports on the development of a spark plasma sintering (SPS)‐assisted sol‐gel method for the synthesis of dense pellets, belonging to the series of InGaO3(ZnO)m homologous phases, where m is an integer. We show that using this synthesis route, the sintering temperature is significantly decreased down to 950–1000°C as compared to ...
