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...

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)...
Ark shell was added to the coal ash as a source of CaO to reduce the melting temperature of the overall mixture, and TiO2 was used as the nucleating agent 这个方法有原则和在描述的“Silceram”方法一样第4.2.2部分。 舟贝增加到煤炭灰作为CaO的来源减少整体混合物的熔化的温度,并且TiO2使用了作为...
Brown Fused Alumina is also called Brown Corundum, it is fused and crystallized under high temperature from a mixture of bauxite and other and other raw materials. It is characterized by its high hardness,good toughness and shape in size. Abrasives tools made of it are suitable fo...
1.During so-lidification of iron inhigh temperature aluminum meltingwith cast iron crucibles,brittle a phase and π phase are generated to wors-en the performance of the aluminum alloy.在铸铁坩埚高温熔铝过程中,铁凝固时会形成脆性的α相和π相,显著降低铝合金的性能。
What criteria should you use to determine whether recrystallization or sublimation will be a better method of purification? Explain how some solids (compounds that are solids at room temperature) can be analyzed by gas chromatography. How do you determine the...
Partialmelting 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. ...
