· Results suggested that a higher CaO + BaO/Al2O3 ratio would lower the melting temperatures of the mold fluxes and the slag system showed a good thermal stability during the melting process with the evaporation less than 5,10% Besides the crystallization behavior was promoted with the increase of CaO + BaO/Al2O3 ratio, which is associated with the reduction of the polymerization degree of the melt structure, …

· CaO–Al 2 O 3 –B 2 O 3 –based mold fluxes have been proposed by many researchers as the most promising mold fluxes in casting of AHSS but still have some disadvantages for example strong crystallization and poor lubrication 6, 8 Because BaO was reported to inhibit the crystallization of mold fluxes, it will be very interesting to investigate the effect of BaO on the properties of CaO–Al 2 O 3 –B 2 O 3-based …
Effects of CaO + BaO/Al2O3 Ratio on the Melting
We have experimentally determined the solidus position of model lherzolite in the system CaO-MgO-Al2O3-SiO2-CO2 CMASCO2 from 3 to 7 GPa by locating isobaric invariant points where liquid coexists with olivine orthopyroxene clinopyroxene garnet and carbonate The intersection of two subsolidus reactions at the solidus involving carbonate generates two invariant points I1A and I2A, which mark the transition from CO2-bearing …
