Fe 5 O 12 )9. Another study of YIG using ball milling method was done by varying sintering temperatures that resulting the enhancement of magnetic saturation due to the grain size improvement10. However, this research observed the influence of nickel doped (x =,,,, )
· The prepared nanocomposite is used for the removal of penicillin from aqueous solution. Results: Two different phases were identified in XRD patterns as hexagonal ZnO and orthorhombic Zeolite with the average crystal size of 86 and 141 nm respectively. The prepared nanocomposite consists of uniform particles with the mean diameter of near 91 nm.

· Scanning electron microscopy revealed the ballmilled SrFe 12 O 19 particles to have sizes varying over several hundred nanometers. XRay powderdiffraction studies performed on the ballmilled particles before sintering clearly demonstrate the occurrence of a pronounced amorphization process.
Metastable tetragonal zirconia, tZrO2, can be produced at RT and at atmospheric pressure by therma1 decomposition of zirconium salts, alkoxides and hydroxide or by ballmilling of monoclinic zirconia, mZrO2. There are some evidences that metastable tZrO2can be also produced by ballmilling of zirconium hydroxide.
· For the milling process, g of the asreceived Nb powder were loaded into two separate hardened steel containers of 125 ml volume with steel balls of mm diameter, in a balltopowder weight ratio of ~ 10:% volume of the hardened steel containers were filled with 5 ml of absolute ethanol that served as the processcontrolling agent.
· In addition, the results of EDX analyzes revealed trace amounts of Fe, probably coming from the applied milling materials of balls and vial. Furthermore, the results of EDX analyses indie that the carbide contains 47. 59 C, Ti, Cr, and Fe (at.%).
Milling was done at room temperature in a polytetra fluoroethylene (PTFE) vial (volume about 35 cm3) using ten hardened steel balls with 10 mm of diameter, keeping powder sample to ball mass ratio at about 1:8 throughout the experiment. The milling process lasted for 5 h with a rotation speed varying from 250 to 350 rpm.
· Highclass doped nanopowder development and design is the first step toward achieving a number of appliions. The fabriion of nanopowders of selenium doped and silver doped zinc oxide nanostructures can be achieved by using active precursors or halide raw materials, active intermediates, or additives [37].
In contrast, there is no reaction during milling (up to 80 h) with ZrO2cup and balls. Fe and ZrO2were the major impurities introduced during milling with stainless steel and ZrO2cups, respectively. The Fe impurity was removed by leaching in 3HCl·HNO3solution for 4 days. Mean grain size less than 7 nm was achieved at the end of milling.

Abstract: Magnetic nanocomposites SmCo5/αFe were synthesized mechanically by highenergy ball milling (HEBM) from SmCo5and 5%wt. of αFe powders. The Xray diffraction analysis reveals the hexagonal 1:5 phase as the main one accompanied by the cubic αFe phase and 2:17 rhombohe dral as the secondary phase.
