Effects of Sintering Temperature on Microstructural Properties of Ni1-xZnxFe2O4 Synthesized by Powder Metallurgy

Powder metallurgy (PM) is a modern manufacturing method that allows high-tech materials, alloys and complex shaped parts to be manufactured with precision and almost without the need for finishing operations such as deburring. PM basically involves powder production, powder processing, forming operations, pressing and sintering or pressure assisted hot consolidation. This paper reports results on Ni1-xZnxFe2O4 produced by powder metallurgy at different sintering temperatures. Ni1-xZnxFe2O4 is an interesting functional magnetic material due to its special properties such as stability, very good dielectric properties, electrical resistivity, low dielectric loss, chemical stability etc. all being important in cutting-edge technology. The use of Ni1-xZnxFe2O4 in diverse fields such as the biomedical field i.e. drug delivery is another vibrant research area. SEM imaging was performed for the structural analysis of the produced bulk sample. EDXRF analyses were performed for elemental composition along with SEM images.
