“…The CT phase is believed not to affect alumina recovery [3], as long as it is stoichiometric. Otherwise, it might incorporate Al in its structure [9] and reduce Al recovery. The leachability is highly dependent on the crystallization path of the slags and the area of primary precipitation [8].…”

“…This allows for continual oxygen diffusion through the metal oxide layer allowing the process to be employed for single crystals of any size. The Ti extraction method also allows for the processing temperature to be raised up to 1300 • C due to the stability of the C12A7-Ti x O 2−x system [71]. This increase in processing temperature leads to an increase in O 2− diffusion in C12A7 resulting in shorter processing times [2].…”

“…Moreover, they have high refractoriness and corrosion resistance and thermal shock stability. [21][22][23][24][25][26][27][28][29] Therefore, in this study, CaAl 12 O 19 -CaTiO 3 composite materials were fabricated using a solid sintering method. The effects of the calcium source and TiO 2 content on the phase composition, properties, and microstructure of the CA 6 -CT materials were investigated in detail.…”

“…In the CaO–Al 2 O 3 –TiO 2 (CA 6 –CT) system, CaAl 12 O 19 and CaTiO 3 have the highest stability. Moreover, they have high refractoriness and corrosion resistance and thermal shock stability 21–29 . Therefore, in this study, CaAl 12 O 19 –CaTiO 3 composite materials were fabricated using a solid sintering method.…”
