Preparation of spinel lithium ferrite by thermal treatment of spray-dried formates

The thermal decomposition of mixtures of complex ferric formate, /Fe 3(HCOO) 6(OH) 2/HCOO.4H 2O, and LiHCOO.H 2O prepared by spray-drying of their water solutions has been investigated. It was shown that the mixtures decompose at lower temperatures than the individual compounds in them. It was estab...

Description
Summary:The thermal decomposition of mixtures of complex ferric formate, /Fe 3(HCOO) 6(OH) 2/HCOO.4H 2O, and LiHCOO.H 2O prepared by spray-drying of their water solutions has been investigated. It was shown that the mixtures decompose at lower temperatures than the individual compounds in them. It was established that stoichiometric Li O, 5Fe 2, 5O 4 can be prepared by slow and careful heating of formate mixture with lithium in excess to the stoichiometric amount (Li:Fe = 1:4, 4). The final product obtained is powdery Li O, 5Fe 2, 5O4 with a large surface area.
