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 ...
Avaliação em escala piloto do comportamento dos produtos pellet feed, pellet screenings e micro pellet em substituição ao sinter feed em uma mistura de sinterização
(Universidade Federal de Minas GeraisUFMG, 2004-06-02)
Pilot scale sintering experiments were performed, aiming at comparing the quality of the sinter produced from a reference sintering blend with that of sinters resulting from other blends, in which the sinter feed in the ...
Effect of green machining on distortion and surface finishing in advanced ceramic
(2012-11-28)
An alternative for grinding of sintered ceramic is the machining on the green state of the ceramic, which presents easy cutting without the introduction of harmful defects to its mechanical resistance. However, after ...
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 ...
The influence of the sintering system on PMN properties
(2003-03-15)
PMN powder samples with PbO excess of 0, 1,2 and 3% were submitted to the pressing and sintering at 1200°C for 4h with a heating rate of 3°C/min. A new sintering system, developed at our laboratories, was used. It allows ...
Pore size evolution during sintering of ceramic oxides
(1990-12-01)
This paper reviews the influence of particle size distribution, agglomerates, rearrangement, sintering atmospheres and impurities on the pore evolution of some commonly studied oxides. These factors largely affect sintering ...

Niobium sintering process using design of experiment: Taguchi`s method
(2015-01-01)
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 ...
Liquid phase sintering of mechanically alloyed Mo-Cu powders
(Elsevier, 2017)
In the Mo-Cu system, Mo has very low solubility in liquid Cu. To reach high densities after liquid phase sintering it is required the solution-reprecipitation step, which induces shape change. One technique that allows to ...
