摘要: Abstract Two systems of copper ferrites, Cu1 − xTixFe2O4 (system 1) and + xTixFe2 2xO4 2), were analogously investigated for 0 ≤ x 0.4. In addition to X-ray IR spectra investigations, the study microstructure, microhardness d.c. conductivity two was achieved. terms data spectra, different cation distributions proposed system 1 2, respectively. For 1, lattice constant found be independent x, while it increases with 2. A drop in grain diameter from 45 μm about 16 is associated a change 0.4 whilst 2 seems composition. The general trends also taken into consideration.
