Zinc ferrite nanocrystals were prepared from an aqueous solution containing metal nitrates and various of concentrations of poly(vinyl pyrrolidone) (PVP), i.e., 0, 15, 40, and 55 g/L, as a capping agent. To stabilize the particles, they were thermally treated at 873 K, as an optimum calcination temperature. The behaviors of the polymeric precursor were analyzed by use of simultaneous thermo-gra...

Magnetic ferrite-based nanoparticles have recently emerged as a promising alternative choice for the treatment of different types cancer. already been used in diagnosis various diseases and drug delivery vehicle. In this study, spinel ferrite were prepared using hydrothermal approach which is simple cost-effective technique. Spinel from variety divalent metals including nickel, zinc, copper cob...

In the present work, thermochemical water splitting with siliconized silicon carbide (SiSiC) honeycombs coated with a zinc ferrite redox material was investigated. The small scale coated monoliths were tested in a laboratory test-rig and characterized by X-ray diffractometry (XRD) and Scanning Electron Microscopy (SEM) with corresponding micro analysis after testing in order to characterize the...

The dielectric and magnetic behaviour and thermal properties of composites based on nickel–zinc ferrite (NZF) filler can be improved by the addition of various types of materials. Amongst others, ferrite–polymer composites have been subjected to a wide range of research, due to their extensive applications: electromagnetic interference shielding, microwave absorption, electrodes and sensors. Cu...

In this paper, sulfuric acid leaching high iron zinc calcine was used to prepare and purify ferrite, temperature roasting method synthetic sol-gel TiO 2 . The properties of the prepared samples ware characterized by XRD, FT-IR, BET, SEM other methods. results show that ferrite is pure purified contains impurities PbSO 4 crystal form prepares at calcination 300~550°C basically same, transformati...
