3.2. Phase structure Fig. 4 shows the XRD patterns for YSZ and ScYSZ coating. The YSZ is composed by tetragonal ZrO2 phase. After plasma spraying, no Sc2O3 was detected, which indicates that Sc2O3 has been dissolved in the YSZ crystal structure because of high temperature (15000 °C)....
High temperatures in hot corrosion environments can induce phase transformations in YSZ coatings, altering their crystal structure and mechanical properties. For example, tetragonal-to-monoclinic phase transformations may occur due to thermal cycling and stress, contributing to coating degradation and ...
Excellent crystal structure avoids bead breakage and reduces the abrasion of mill parts Applications Application Scenario 1. Bio-tech (DNA, RNA & protein extraction and isolation) 2. Chemicals including Agrochemicals e.g. fungicides, insecticides and herbicides 3. Coating,...
The crystal structure of the LSM powder was then determined by XRD Ohmic resistance The addition of YSZ to the LSM cathode has marked effect on the ohmic and polarization resistances. Fig. 2 shows the ohmic (Rb) and polarization (Rp) resistances as a function of YSZ content. The ohmic ...
The morphology, crystal structure and reducing process of the products were studied by TPR,XRD and TEM etc. The conductivity of Ni-YSZ with different Ni content was determined through the Four-terminal electrode method. The results showed that the products were small diameter,narrow size ...
Crystal structure, Infrared (IR) absorption bands and microstructure of deposited thin films were determined by X-ray diffraction (XRD), Fourier Transformed Infrared Spectroscopy (FTIR), AFM and SEM, respectively. The thermal diffusivity of YSZ coatings onto silicon substrate was determined by the ...
The synthetic cubic zirconia is a hard, colorless, and optically flawless crystal. Because of its low cost, durable, and similar appearance to diamonds, cubic zirconia gemstones have been the most important substitutes for di...
