The sintering additives such as Al2O3 and/or Y2O3 were coated on the surfaces of Si3N4 particles via heterogeneousnucleation processing using a buffered pH solu
With rapid progressive application of TiO2 thin films,magnetron sputtering becomes a very interesting method to prepare such multi-functional thin films.This pa
In this paper, the critical pressure Pcrit and impeding pressure Pirnpe of the elemental evaporation were defined and studied based on the calculation of the re
