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 ...
The thermodynamic parameters have been assessed for the systems of ZrO 2 – Y 2 O 3 , ZrO 2 –Al 2 O 3 and ZrO 2 –Y 2 O 3 –Al 2 O 3 using the Calphad technique. The solid solutions are described by the compound energy formalism. A two-sublattice ionic
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 ...
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 diagrameutectic materialsThe liquidus surface on the Al 2 O 3 –HfO 2 –Y 2 O 3 phase diagram is constructed for the first time. No ternary compounds and appreciable solid solution regions based on components and binary compounds are found in the ternary system. The liquidus surface is...
