Phase equilibria in the TiO2–YO1.5–ZrO2 system Isothermal sections of the TiO 2–YO 1.5–ZrO 2 phase diagram at 1300, 1500 and 1600 °C were studied experimentally using pre-alloyed powders prepared by ... TA Schaedler,O Fabrichnaya,CG Levi - 《Journal of the European Ceramic Society》...
TiO2 nanoparticles acquire complete crystalline anatase phase on thermal treatment of as-prepared anatase TiO2 at 450°C. Anatase-rutile mixed phase and rutile phase are achieved by annealing anatase TiO2 at 700°C and 950°C respectively. The anatase-rutile mixed phase TiO2 has 87.8% rutile phase...
According to the phase diagram of STO, oxygen deficient STO34–36 is (expected in grain boundary regions) phase known to be a good semiconductor. For non-stoichiometric separation and the formation of either Ruddlesden-Popper SprhTaisOes3 (Sr-rich)37,38 or Magnéli type phases (Ti-rich)39 ...
Optimised calculations of phase diagram (PD) and thermodynamic properties of the Ni-Cr system were carried out in [12]–[14] The incorrect topology of phase diagram was obtained in these works (the eutectic diagram with two points of the equal concentration for L/Fcc equilibrium). There are ...
Results Phase diagram. Detailed enthalpy calculations for the most stable structures allowed us to reconstruct the pressure-composition phase diagram (Fig. 1). The first thermodynamically stable carbon nitride, P42/m-CN, appears at the pressure of just 14 GPa. This is a superhard 3D-polymeric ...
Phase relations in the system of (Na1/2Bi1/2)TiO3–PbTiO3. I. Structure The region of the (Na1/2Bi1/2)1x Pb x TiO3phase diagram from 0≤x≤0.2 was established through analysis of structure and thermal anomalies associated with ... Seung‐Eek,Park,Kug,... - 《Journal of Applied...
