Abstract In this work, the influence of the second phase fine powders on solid state sintering process was in situ investigated by synchrotron radiation X-ray computed tomography (SR-CT) technique. Microstructure evolution of the pure SiO2 powders and SiO2 powders mixed with Si3N4 fine powders during sintering is observed respectively from the SR-CT reconstructed images.
Sintering process, as the final and the most crucial step for the preparation of various ceramic materials, will inevitably affect the microstructure and properties of the material. The inclusions with different kinds or particle size may promote or hinder the sintering process. Mixed… More >
