Influence of BaO and MgO on viscosity, crystalline phase, and structure of CaO–Al2O3–10%SiO2–20%CaF2-based system

Effect of High Mass Ratio of CaO to Al2O3 on Properties of Slag Containing 10% SiO2

“…A schematic representation of the experiment equipment was depicted everywhere. [16] Before the measurement, calibration of the viscometer was conducted utilizing standard silicone oils of 0.096, 0.495, and 0.996 Pa s, respectively, all of which were maintained at 298 K. The pre-melted powders, weighing 250 g, were added to a high-purity graphite crucible within the MoSi 2 furnace at 1673 K. Subsequently, the mixture was held for 20 min under an argon atmosphere. The Mo spindle, rotating at a rate of 12 rpm, was then submerged into the liquid slag to measure the viscosity.…”
