Compacting and densification of TiO2 nanoparticles Abstract: This work investigated the compacting and densification behaviour of TiO2 nanoparticles prepared by the simple non-aqueous sol-gel process. The synthesized nanopowder has anatase TiO2 structure with the average crystallite […]
A versatile approach for the preparation of ceramics with porosity gradient: by using manganese and tin oxides as a model Abstract: Porous ceramics that exhibit porosity gradient are considered promising materials from the industrial point of […]
Writers: R. M. Batista; E. N. S. Muccillo Keywords: TG; DRX; Ceria; Dilatometry; Sintering Abstract: The sintering process of compacts of nanostructured gadolinia-doped ceria was investigated by dilatometry and by construction of the master sintering curve. Corrections for the thermal expansion of the experimental setup and mass […]
