Hot-pressed 9.5/65/35 PLZT prepared by the polymeric precursor method
(Elsevier B.V., 2000-01-01)
A 9.5/65/35 PLZT ceramic with a Pb-0.905 La-0.095 (Zr-0.65 Ti-0.35)(0.976) O-3 + 35 w% PbO formula was prepared using the Pechini method for powder preparation and two-step sintering in an oxygen atmosphere. Thr first step ...
Hybrid material based on an amorphous-carbon matrix and ZnO/Zn for the solar photocatalytic degradation of basic blue 41
(2020-01-01)
Innovative composites based on an amorphous-carbon matrix containing a second phase ZnO oxide and/or highly dispersed Zn metallic were synthesized via a modified Pechini route, in which a partial pyrolysis method was ...
Spectroscopic properties of pigment Li2-xZn1-xPrxTi3O8
(2016-07-01)
Inorganic compounds doped with rare earths (Ce3+ Pr3+ Nd3+ Sm3+ Eu3+ Gd3+ Tb3+ Tm3+) have been used in various applications including light-emitting devices such as fluorescent lamps, cathode ray tubes, lasers and inorganic ...
Direct ethanol fuel cell: Electrochemical performance at 90 degrees C on Pt and PtSn/C electrocatalysts
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Carbon-supported Pt-based electrocatalysts were synthesized by Pechini method for the ethanol oxidation (EOR). Physicochemical characterizations were helpful to estimate the diameters of the obtained materials ranging from ...
Effect of W on PtSn/C catalysts for ethanol electrooxidation
(SPRINGER, 2008)
Binary and ternary Pt-based catalysts were prepared by the Pechini-Adams modified method on carbon Vulcan XC-72, and different nominal compositions were characterized by TEM and XRD. XRD showed that the electrocatalysts ...
Sinterização e caracterização de segunda fase em sistemas SnO2-ZnO
(Associação Brasileira de Cerâmica, 2005-09-01)
A adição de ZnO em sistemas de SnO2 faz com que estas cerâmicas atinjam elevada densificação quando adicionadas em baixas concentrações. Neste trabalho estudou-se o comportamento da adição do óxido de zinco desde 0,5 até ...
