Some solid solutions with the chemical composition KxFeyTi8-yO16 (KFTO) and a hollandite-like structure were successfully synthesized by modified sol–gel method. The obtained powders characterized using X-ray diffraction (XRD) scanning electron microscopy (SEM). ceramic pellets based on KFTO compressing sintering at 1080 °C for 4 h. sinters impedance spectroscopy. XRD results show that have mon...

Oxygen carrier aided combustion is a process that utilizes oxygen carrying particles in fluidized bed to transport from oxygen-rich oxygen-poor regions the reactor. A commonly used oxygen-carrying material ilmenite (FeTiO3) which naturally occurring mineral. At higher partial pressures can react pseudobrookite (Fe2TiO5) and thereby take up oxygen. Upon reduction of oxygen-lean locations release...
