Anisotropy of crystallite growth during sintering of SnO2 xerogels
(1996-12-01)
The crytallite and pore-size evolution during isothermal sintering (400 ≤ T ≤ 700°C) of SnO2 xerogels was studied by X-ray line broadening and nitrogen adsorption-desorption isotherms. The experimental results show a strong ...
EXAFS and XRD Study of the Structural Evolution during Isothermal Sintering of SnO2 Xerogels
(1997-12-01)
The formation of an ordered (crystalline) phase during isothermal sintering of SnO2 monolithic xerogels, at 200, 250, 300, 400, 500, 600 and 700°C, has been analyzed by the combined use of EXAFS and XRD techniques. For the ...
Isothermal sintering kinetic of 3YTZ and 8YSZ: Cation diffusion
(Elsevier, 2013-01)
We have studied the sintering kinetic of 3 and 8 mol% of yttria stabilized zirconia under isothermal conditions. Sintering was performed in the temperature range between 1200 and 1450 °C. The sintering kinetic process was ...
POROSITY EVOLUTION IN SNO2 XEROGELS DURING SINTERING UNDER ISOTHERMAL CONDITIONS
(American Physical Soc, 1995-04-01)
Evolution of the fractal structure during sintering of SnO2 compacted sol-gel powder
(1995-04-28)
The structural evolution during sintering of compacted SnO2 sol-gel powder was investigated using nitrogen adsorption isotherm analysis. Results show that for sintering temperatures up to 400°C the samples have a fractal ...
Effect of atmosphere on the sintering and grain growth of tin oxide
(1999-12-01)
High purity SnO 2 powder (>99.9%) was compacted in cylindrical pellets and sintered in atmospheres of dry argon, argon with water vapor, oxygen and CO 2 using 10 °C/min up to 1200 °C or isotherms in the range of 1000 to ...
Porosity evolution in SnO2 xerogels during sintering under isothermal conditions
(1995-01-01)
The structural evolution during isothermal sintering (200≤T≤600 °C) of SnO2 xerogels was studied by small-angle x-ray scattering (SAXS) using synchrotron radiation. The SAXS intensity and, consequently, the structure ...
Sintering of undoped SnO2
(Associação Brasileira de Cerâmica, 2003-04)
Pure SnO2 sintering was studied by constant heating rate and isothermal sintering. The constant heating rate study showed no macroscopic shrinkage during the sintering process up to 1500 ºC. Pore size distribution measurements, ...
Free and constrained sintering of 3-mol % yttria stabilised zirconia
(Universidad Nacional de Colombia Sede Medellín, 2014-01-22)
Densification and shrinkage behaviour of ceramics or other powder materials can be predicted in a simple manner by using the master sintering curve. In this work, the densification data required to construct the master ...
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 ...
