The viscosity declines and the viscosity curve are transformed from crystalline slag to glassy slag with increasing mass ratio (C/F) of calcium to ferrous oxide in Al 2 O 3 -SiO 2 -CaO-FeO system. There is an inflexion point when the C/F is equal to 2. When the C/F is below 2, there are mainly crystalline minerals in the system. While the C/F is above 2, there are mainly amorphous minerals in the system. With the increase of C/F, six-coordinated Al ([AlO 6 ] 9− ) is transformed to four coordinated Al ([AlO 4 ] 5− ) microscopically. Besides, the content of bridging oxygen decreases while that of non-bridging oxygen increases. Quantified function between base composition and viscosity are constructed based on the stability coefficients defined by oxygen bond species.","claims":[{"public_id":"cl_23db235c9cbed3c77e45b082fff78589","status":"active","text":"A quantified function relating base composition to viscosity was constructed for the Al2O3-SiO2-CaO-FeO
