| Abstract: | Nanosized nickel ferrite spinel particles have been synthesized by a precursor approach in the condition of ultrasound radiation. Sonicating an aqueous solution of nickel nitrate,ferric nitrate and urea yields a precursor. This precursor was then heated at 950 ℃ for 15 h to yield nanosized NiFe2O4 particles with a average size of 15 nm. The nanosized nickel ferrite particles have been characterized by powder X-ray diffraction,transmission electron microscopy and FT-IR. The result showed that the product by sonochemical method was nanosized NiFe2O4 particles. |
