Preparation and electrical properties of xCaRuO3/(1−x)CaTiO3 perovskite composites

Development of the Fray-Farthing-Chen Cambridge Process: Towards the Sustainable Production of Titanium and Its Alloys

“…S4a and S4b). 59,75,76 However, CaRuO 3 alone is too expensive to use, whilst CaTiO 3 is too resistive. Therefore, the cheaper CaTiO 3 and the highly conductive CaRuO 3 were utilised to form the solid solution of CaTiO 3 -CaRuO 3 , i.e., CaTi xRu 1Àx O 3 , which was then made into the inert anode for titanium and titanium-nickel (Ti-Ni) alloy production.…”

DC Voltammetry of Electro-deoxidation of Solid Oxides

“…"For a 5.5 cm 2 anode surface area, the current efficiency was calculated to be 55% for the SnO 2 -based material at 3 V; compared with 30% and 50% for graphite at 3 V and 2 V, respectively". 86 Similarly, upon using SnO 2 -based anode in the electro-deoxidation of Ta 2 O 5 , the charge passed was 10300 C, while 17100 C being passed with a graphite anode. 87 Considering the theoretical charge required to reduce 1.9 g of Ta 2 O 5 is 4423 C, then the current efficiency is 40% with the SnO 2 -based anode and 24% with the graphite anode.…”

Proving the viability of an electrochemical process for the simultaneous extraction of oxygen and production of metal alloys from lunar regolith

“…In their study, Schwandt et al (2012aSchwandt et al ( , 2012b showed that oxygen could be obtained by the FFC-Cambridge electrolysis of pellets of the mineral ilmenite at 900 °C using an inert anode (either doped tin oxide (Kilby et al, 2010) or a calcium titanate/calcium ruthenate mixture (Jiao et al, 2009;Jiao and Fray, 2010)). The authors also described the electro-generation of oxygen from pellets of the lunar simulant JSC-1.…”
