SnO 2 ceramics with low electrical resistivity obtained by microwave sintering
(2011-08-01)
The main aim of this study was to develop dense and conducting SnO 2 ceramics without precipitated phases on the grain boundaries, which was verified using field emission scanning microscopy (FE-SEM) coupled with an ...

Sintering and Microwave Properties of Zirconium Tin Titanate Doped with Select Oxides
(SPRINGERNEW YORK, 2012)
Zirconium tin titanate (ZST) is often used as a dielectric resonator for the fabrication of microwave devices. Pure compositions do not sinter easily by solid state sintering; therefore, sintering ZST requires sintering ...
Effect of atmosphere and dopants on sintering of SnO2
(2002-12-01)
Tin oxide is an n type semiconductor material with a high covalent behavior. Mass transport in this oxide depends on the surface state promoted by atmosphere or by the solid solution of aliovalent oxide doping. The sintering ...
High-temperature diametral compression strength of microwave-sintered mullite
(Elsevier, 2011-08-15)
The mechanical strength of mullite materials sintered by the conventional route or by microwave was evaluated by diametral compression at room temperature and 1400 ◦C. Crack patterns and fracture mechanisms were analyzed ...
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 ...

High versus low altitude hot spring settings and associated sinter textures from El Tatio, Chile, and the Taupo Volcanic Zone, New Zealand
(2012)
Hot alkali chloride fluids ascend from deep geothermal reservoirs and discharge at the surface as hot springs. As the silica-rich fluid discharges and cools to below 100°C, the silica carried in solution precipitates and ...
