Electron Holography of Charging Effect in ZrO2 Sintered Body
The effects of charging on a ZrO2 sintered body due to electron irradiation were investigated by means of electron holography. The charging effects were quantitatively evaluated as a function of the incident electron density. The ZrO2 sintered body was positively charged within a transmission electron microscope. By means of simulations taking into account reference wave modulation due to a lon...
متن کاملMicrostructure and Mechanical Properties of Microwave Sintered ZrO2 Bioceramics with TiO2 Addition
The microwave sintered zirconia ceramics with 0, 1, 3, and 5 wt% TiO2 addition at a low sintering temperature of 1300°C and a short holding time of 1 hour were investigated. Effect of contents of TiO2 addition on microstructure and mechanical properties of microwave sintered zirconia bioceramics was reported. In the sintered samples, the main phase is monoclinic zirconia (m-ZrO2) phase and mino...
متن کاملNew phase of ZrO2 created by swift heavy ion irradiation at high pressure
Zirconia (ZrO2) is a commonly used ceramic which is known for its thermal and mechanical resistance and its radiation hardness. Because of these properties it is often used as inert fuel matrix in nuclear reactors [1]. At ambient conditions the material is in its monoclinic form which it changes to tetragonal at ~ 1200°C and to cubic at ~2400°C. High pressure forms are known to be orthorhombic....
متن کاملProperties of nanostructured diamond-silicon carbide composites sintered by high pressure infiltration technique
A high-pressure silicon infiltration technique was applied to sinter diamond–SiC composites with different diamond crystal sizes. Composite samples were sintered at pressure 8 GPa and temperature 2170 K. The structure of composites was studied by evaluating x-ray diffraction peak profiles using Fourier coefficients of ab initio theoretical size and strain profiles. The composite samples have pr...
متن کاملPreparation of High Surface Area ZrO2 Nanoparticles
In comparison to the previous researches, ZrO2 nanoparticles with higher surface area (85 m2/g) have been synthesized in this research. The as-prepared ZrO2 nanoparticles by co-precipitation method were characterized with X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). The surface area of the s...
