All three phases in the binary YO–AlO-phase diagram (YAlO, YAlOand YAlO) and α-alumina are located by EBSD. Energy dispersive X-ray spectrometry results obtained from these microspheres show that their chemical composition can deviate from the nominal composition of the precursor powder. The ...
The ternary phase diagram of the AlN-Al2O3-Y2O3 was developed by Gibbs energy minimization using interpolation procedures based on the modelling of the binary subsystems. Binary diagrams of Al2O3-Y2O3, AlN-Al2O3, and AlN-Y2O3 were thermodynamically modelled. The calculated Gibbs energies of ...
Four quarternary phase regions occur in this system: H Si3N4 Y2O3·Si2N2O 3Y2O3·5Al2O3 H Si3N4 3Y2O3·5Al2O3-O′ss H Si3N4 O′ ss Si2N2O H Y2O3·Si2N2O 3Y2O3·5Al2O3 4Y2O3·Si2N2O·Al2O3 From the results of this work, the sub-solidus phase diagram and the isothermal ...
The primary glass is converted into glass-ceramic by thermally formed nano-crystalline phase dispersed thorough a glass matrix [1], [2]. In new transparent glass-ceramics, the optically active rare earth ions distribute into fluoride crystal phase that results in an economical alternative with ...
It is shown that the phases formed during reactive diffusion do not uniquely correspond to the phase diagram, but depend on the initial structure of contacting layers and the type of heating. This is attributed to the contribution of kinetic factors to the competitive phase growth, particularly ...
The phase diagram of the Al2O3–Y2O3 system has been investigated with five different compositions by XRD and in situ high temperature neutron diffractometry. High purity YAG, YAP and YAM compounds have been produced successfully through a melt extraction technique. High temperature neutron ...
phase diagramThe isothermal sections of the Al2O3-TiO2-Y2O3 phase diagram are constructed for the first time at 1550 and 1400 degrees C. New phases or appreciable homogeneity ranges based on components and binary compounds are not found in the ternary system. Triangulation of the system is ...
The phase diagrams of the ZrO2-Y2O3 and ZrO2-Al2O3 and Y2O3-Al2O3 systems are in fairly good agreement with phase equilibrium data. Isothermal sections of the phase diagram of the ZrO2-Y2O3-Al2O3 system at subsolidus conditions are calculated. Introducing ternary interactions in the liquid ...
