Effect of the sintering conditions on the electrical properties of Nd(3+) modified PLZT ceramics
(Iop Publishing Ltd, 2008-02-21)
The effect of the sintering method on the microstructural and electrical properties of (Pb(0.89)Nd(0.02)La(0.09))(Zr(0.65)Ti(0.35))O(3) (PNLZT) ceramics was studied by impedance spectroscopy. Structural and microstructural ...
Microstructural evolution during sintering of CoO doped SnO2 ceramics
(Elsevier B.V., 1999-01-01)
Addition of 0.5 mol% of CoO into SnO2 promotes densification of this oxide to 99% of the theoretical density during sintering. TEM in this system reveals that after sintering at 1210 degrees C a secondary phase of Co2SnO4 ...
Impedance spectroscopy of SnO2: CoO during sintering
(Elsevier B.V., 1997-01-01)
SnO2:m mol% CoO (0.5 less than or equal to m less than or equal to 6.0) ceramic specimens were studied by impedance spectroscopy in the 5 Hz-13 MHz frequency range during heating cold-pressed specimens from room temperature ...
Sensitivity of SnO2 non-ohmic behavior to the sintering process and to the addition of La2O3
(Elsevier B.V., 2001-09-01)
The work reported here consisted of a study of the sensitivity of the nonlinear electrical properties of dense SnO2. CoO ceramic systems to low concentrations of La2O3, sintering temperature and cooling rates. The nonlinear ...
High temperature X-ray diffraction study of the U4O9 formation on UO2 sintered plates
(1991-01-01)
The surface oxidation of UO2 sintered plates at 170-275 ° C was studied in situ by high temperature X-ray diffractometry. At very low oxygen concentration, UO2 is oxidized to U4O9, while at 300°C and argon-20 vol% oxygen ...
Isochronal sintering of the blended elemental Ti-35Nb alloy
(Elsevier B.V. Sa, 2008-01-15)
Titanium alloy parts are ideally suited for advanced aerospace systems and surgical implants because of their unique combination of high specific strength at both room temperature and moderately elevated temperature, in ...
Formation of SnO2 supported porous membranes
(Kluwer Academic Publ, 1997-01-01)
In this work, the effect of the substrate microstructure on the formation of SnO2 membranes and of the sintering conditions on their porosity have been analysed. Samples have been prepared by colloidal suspensions cast on ...
Compositional Design of Dielectric, Ferroelectric and Piezoelectric Properties of (K, Na)NbO3 and (Ba, Na)(Ti, Nb)O-3 Based Ceramics Prepared by Different Sintering Routes
(Mdpi Ag, 2016)
Lead free piezoelectric materials are being intensively investigated in order to substitute lead based ones, commonly used in many different applications. Among the most promising lead-free materials are those with modified ...
