Samples of the nominal composition Ti1 - (x)(BP)(x/2)O-2 were synthesized by the gel combustion method and studied by X-ray powder diffraction analysis and IR spectroscopy. Based on the data obtained, the diagram of the TiO2-B2O3-P2O5 system was constructed, which describes phase ...
Coupling these observations with powder X-ray diffraction and transmission electron microscopy allowed new insights into the barium oxide (BaO)–titanium dioxide (TiO2) phase diagram. The transition temperature was varied systematically with the Ba/Ti ratio at annealing temperatures from 1200° to 1400...
First-principles calculations of the crystal structures, bulk moduli, and relative stabilities of seven known and hypothetical TiO2 polymorphs (anatase, rutile, columbite, baddeleyite, cotunnite, pyrite, and fluorite structures) have been carried out with the all-electron linear combination of atomic ...

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》...
(1992), but in striking contrast to the phase diagram inferred by Olsen et al. (1999). The natural occurrence of TiO 2 II requires formation pressures considerably higher than the graphite–diamond phase boundary. 展开 关键词: 3-D resistivity forward modeling finite-element secondary potential ...
The phase diagram TlI-BiI 3 shows the two stable compounds Tl 3 Bi 2 I 9 and Tl 7 Bi 3 I. Twinning prevents a full determination of the structures. Large single crystals of Tl 7 Bi 3 I are obtained by the Bridgman technique. By sensitive piezoelectric and electrooptic measurements the...
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 ...
The binary mixtures of ibuprofen and stearic acid have been tested on the DSC at a heating rate of 5°C min 1. All temperatures reported here are for endothermic peak temperatures. The heating curves are employed to construct a phase diagram. The resultant phase diagram shows the existence ...
Multicritical Nishimori point in the phase diagram of the ±J Ising model on a square lattice We investigate the critical behavior of the random-bond ±J Ising model on a square lattice at the multicritical Nishimori point in the T-p phase diagram, ... Martin,Hasenbusch,Francesco,... - ...
