A study of sintering and magnetic parameters of spinel lithium ferrite; I. Pure lithium ferrite

Abstract

Powdery spinel lithium ferrite, Li 0.5Fe 2.5O 4, was prepared from a mixture of complex ferric formate and lithium formate at different temperatures ranging from 300 to 700°C. The largest specific surface areas were established with samples obtained at 500°C. The highest density, reaching 98% of the theoretical lithium ferrite density, was found with the same samples on sintering at 1100°C. Some magnetic parameters of the high-density samples were measured.
