The effect of calcination temperature on the characteristics and propertiesof titanium dioxide

In this study, ilmenite soil particles in Gharaghaj Urmia were measured using the leachingmethod with hydrochloric acid to obtain high-quality and pure titanium dioxide pigment. The studyinvolved several stages, including leaching with ۳۷% HCL acid, hydrolysis, crystallization, andcalcination. The calcination stage was investigated in this study, which is one of the most importantstages in producing this white pigment. Calcination is a thermal operation on solid materials thatis used for thermal phase decomposition or removal of volatile substances. Temperature, pressure,and calcination conditions can all affect the structural and photocatalytic properties of the particlesobtained from ilmenite soil. Different methods exist for ilmenite calcination, depending on thespecific conditions and process requirements. XRF, SEM, EDX, and XRD analyses wereperformed on the primary concentrate and final calcined product under different conditions.
