Doping CdO helps Nb_2O_5 and Dy_2O_3 dissolve and diffuse, reducing material's sintering temperature effectively, raising dielectric constant ,improving the shape look of crystal grain of ceramics, restraining crystal grain from growing up.
Its structure was characterized by elemental analysis, diffuse reflectance infrared Fourier transform spectroscopy, and thermal analysis.
The catalyst samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis DRS).
The results of attenuated total reflectance FTIR spectroscopy (ATR-FTIR) showed that PP-g-PEG could diffuse preferably onto the surface of the blends and be suitable as an effectual macromolecular surface modifier for PP.
Melting point depressants (B, Si) diffuse far away from the joint and the base metal element is homogenous across the joint.
The effect of hydrogen on the susceptibility is more obvious in the low stress region due to the longer fracture time, which resulted in a longer time for more hydrogen to diffuse toward the crack tip.
