Anisotropy of crystallite growth during sintering of SnO2 xerogels
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 ...
Evolution of the fractal structure during sintering of SnO2 compacted sol-gel powder
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-temperature diametral compression strength of microwave-sintered mullite
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 ...
Microstructural development of ZnO varistor during reactive liquid phase sintering
The microstructural evolution, grain growth and densification for the varistor systems ZnO-Bi2O3 (ZB), ZnO-Bi2O3-Sb2O3 (ZBS), ZnO-Bi2O3-Sb2O3-MnO-Cr 2O3-CoO (ZBSCCM) were studied using constant heating rate sintering, ...
