Preparation and Structural Characterizations of Titania Slag

Preparation and Structural Characterizations of Titania Slag

The thermal stability, crystal structures, microstructure, surface chemical functional groups and molecular structures of titania slag were characterized using TG/DSC, XRD, SEM, FT-IR and Raman spectroscopy techniques, respectively. Occurrence of two phase transformation of titania slag was identifi...
