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 ...

In the last years it has been used statistical tools for industrial optimization processes, research and development, in order to minimize the amount of experiments and to establish the best relationships among representative ...
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 ...
