| الوصف: | A stabilized zirconia oxygen probe was used to measure the oxygen partial pressure (OPP) at an electrode submerged in a copper slag melt at 1300 ℃. The OPP was controlled in the range of 10−10–10−5 atm owing to the presence or absence of a powdered carbon layer on the slag melt using a high-purity alumina crucible in argon (Ar) gas flow. Under suppression of magnetite formation at an OPP of approximately 10−10 atm, the viscosities of the copper slag and FeO-Fe2O3-SiO2-Al2O3 slag melts were measured between 1200 ℃ and 1300 ℃. The obtained values were in the range of 1.0×102–7.8×102 mPa・s. The dependences of total Fe/SiO2 mass ratio and Al2O3 concentration on viscosity were qualitatively interpreted from the aluminosilicate network structure viewpoint. |
