A study on electronic conductivity of CaO-SiO_2-Al_2O_3-FeO_x slag system with Wagner polarization technique was carried out.The experimental data show that electronic conductivity is consisted of free electron conductivity and electron hole conductivity and both are related to the content of Fe~(3+) and Fe~(2+).Free electron conductivity is decreasing and electron hole conductivity is increasing while Fe~(3+) changes to Fe~(2+).There is a maximum electronic conductivity at some ratio of ferric ions Fe~(3+) to total ion content.Under the experimental conditions,the electronic conductivity is in the range of 10~(-4)—10~(-2) S/cm.
A study on electronic conductivity of CaO-SiO_2-Al_2O_3-FeO_x slag system with Wagner polarization technique was carried out. The experimental data show that electronic conductivity is consisted of free electron conductivity and electron hole conductivity and both are related to the content of Fe ~ (3+) and Fe ~ (2 +). Free electron conductivity is decreasing and electron hole conductivity is increasing while Fe ~ (3+) changes to Fe ~ (2 +). There is a maximum electronic conductivity at some ratio of ferric ions Fe ~ (3+) to total ion content. Un der the experimental conditions, the electronic conductivity is in the range of 10 ~ (-4) -10 ~ (-2) S / cm.
