摘要

Liquidus temperatures and phase equilibria have been determined in the olivine primary phase field of the MgO-"FeO"-SiO_2-Al_2O_3 system, Liquidus isotherms have been determined in the temperature range from 1 748 to 1 873K. The results are presented in the form of pseudo-ternary sections of the MgO-"FeO"-SiO_2 with 2 and 3 wt percent Al_2O_3 in the liquid. The study enables the liquidus to be described for a range of SiO_2/MgO ratios. It was found that liquidus temperatures in the olivine primary phase field decrease with the addition of Al_2O_3.
