TiO2-BaO-SiO2 glass have been prepared by melt quenching method. The enhancement of glass coloration was observed as melting temperature increase. UV-Vis-NIR spectrophotometer reveals the change of glass transmittance. And the Ti2p(3/2) and O1s XPS results shows that Ti ions exist in the Ti3...
TiO2–BaO–SiO2glass have been prepared by melt quenching method. The enhancement of glass coloration was observed as melting temperature increase. UV-Vis-NIR spectrophotometer reveals the change of glass transmittance. And the Ti2p3/2and O1sXPS results shows that Ti ions exist in the Ti3+and ...
Plasma electrolytic oxidation (PEO) process was used to incorporate TiO2 and ZrO2 particles into a magnesium oxide layer. Whereas incorporated ZrO2 particles were clearly observed in the PEO-treated oxide layer, TiO2 particles were scarce in the oxide layer because the temperature of the plasma was...
In summary, the speaker is conducting experiments on a 99.9% TiO2 source powder and is looking for ways to lower its melting point without compromising its purity. They only have access to an electrical furnace with a maximum temperature of 1200 degC and have tried lowering the pressure using ...
The melting temperature increases with the Ti core radius. The trend agrees well with the theoretical phase diagram of bimetallic nanoparticles. In addition, the glass phase formation of Al–Ti nanoparticles for the fast cooling rate of 12 K/ps, and the crystal phase formation for the low ...
The melting temperature of iron plays a key role in determining the core dynamics and understanding the thermal history of the planet. However, both the experimental and theoretical work on the melting properties of the lower-mantle components and of iron at the inner–outer core boundary (IOCB)...
The phase change is modeled using a temperature-transforming model and shrinkage induced by melting is also taken into account. The problem appears to be steady-state since it is formulated in a coordinate system moving with the Gaussian heat source and the size of the powder is much larger ...

Partial melting experiments at high temperature and high pressure in combination with thepetrochemistry data show that the starting melting temperature of rocks tends to increase with in-crcasing FeO +MgO+CaO+TiO2 and Al2O3 and decreasing K2O+Na2O and SiO2 in an anhydroussystem. 高温高压熔融实验...
