With the continued exploitation and utilization of high-grade rare earth ores, it is increasingly important to extract earths from separated slag containing low-grade earth. The X-ray powder diffraction, scanning electron microscopy, probe micro-analyzer confocal laser microscopy were used explore influence TiO2 cooling rate on crystallization CaO-SiO2-TiO2-10 wt% P2O5-8 Nb2O5-5 CeO2-5 CaF2 system. In this study, britholite was precipitated selectively as Ce-enriched phase. When added at...
In order to utilize niobium concentrate of Bayan Obo effectively, the effect Nb 2 O 5 and basicity on viscosity CaO-SiO -Nb -5.0 wt.% CeO CaF slag system was studied from 1653 1813 K in reducing atmosphere by rotating cylinder method. For same condition, as-quenched samples were investigated through X-ray diffraction Raman spectroscopy. The results show that viscosity, break temperature activation energy viscous flow decrease with increase basicity. spectra 4+ ions exist form [NbO 6 ]...
Developing efficient membranes for He separation and purification is a key application-oriented technology future innovative engineering. The performance of the T-C3N2 monolayer from gas mixture (He, Ne, Ar, CO, N2, CO2, H2O, CH4) was systematically investigated by combination MD simulations DFT calculations. It found that pure exhibits high permeability but poor selectivity He/Ne He/CO2, which motivates us to introduce biaxial compressive strain in improve performance. Under 5% at 300 K,...
The rare earth in the slag can be separated and enriched by heating melting then slowly cooling crystallisation. In this process, it is of great significance to study effect chemical composition on crystallisation phase viscosity crystal growth. melt samples were prepared according main using an analytical pure reagent. effects CaF 2 La O 3 contents structure morphology CaO–SiO –La –CaF slags studied SEM-EDS XRD. relationship between growth behaviour was measuring with cylinder rotation...
In this article, we report a way to produce sintered bricks from industrial coal gasification slag.
