2019年1月15日 · Al 2 O 3 -modified YSZ (Y 2 O 3 -stabilised ZrO 2) coatings can resist it. Here, the effect of the Al 2 O 3 content in YSZ on the resistance of CMAS corrosion was investigated by means of differential scanning calorimetry (DSC), X-ray diffraction (XRD) and wetting tests.

2020年3月1日 · Differential scanning calorimetry (DSC) was used to detect the heat change of the composite ceramic during heat treatment. The properties of the La 2 Zr 2 O 7 @YSZ composite ceramic, such as the thermal conductivity, coefficient of thermal expansion (CTE), and mechanical properties were investigated using a laser flash method, high-temperature ...

2019年7月1日 · Herein, we investigate the thermally induced phase transitions of ZrO 2 and yttria-stabilized zirconia (YSZ) monolithic aerogels. All aerogels were produced by an acid-catalyzed sol-gel technique and subsequent supercritical drying (SCD). A complete reaction mechanism is proposed for the formation of the wet gel network.

2020年9月12日 · In the present work, Yttria Stabilized Zirconia (YSZ) was synthesized rapidly through microwave combustion. Subsequently, the synthesized YSZ was conventional sintered at different temperatures, ranging from 1200 to 1400 ºC at 50 °C intervals. X-ray diffraction results confirmed that the synthesized YSZ belongs to the cubic phase.

2016年4月22日 · The synthesized YSZ nano-clusters were characterized by TG, DSC, FT-IR XRD, Raman spectroscopy and TEM in order to evaluate the crystal structure, thermal behavior and morphological assessment of the final nano-clusters produced by this method.

La2O3 and Y2O3 co-doped ZrO2 (La-YSZ) TBCs and yttria-stabilized zirconia (YSZ) TBCs were deposited by atmospheric plasma spraying (APS), and the comprehensive effects of La3+ on the ...

2012年3月1日 · In the present study, we investigated the effect of interfaces on the YSZ crystallization process in YSZ/Al 2 O 3 multilayers using DSC. Compared to Al 2 O 3, the transition of amorphous YSZ is more distinct, occurs at lower temperatures, and produces only one crystalline phase.

In this study, nano-YSZ was produced using a wet chemical method to improve the phase stability of micro-YSZ. The phase stability of both synthesized nano-YSZ and commercially available...

2018年3月1日 · Characterization techniques including high-temperature XRD (up to 1050 °C), Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA) (up to 1300 °C) allowed assessing the changes in phase contents, specific heat, thermal conductivity and enthalpy of the TC.
