Theoretical and experimental evaluation of particle size effect of iron, cobalt, and nickel powders suspended in al Dura oil on XRF intensities

الملخص EN

Iron , Cobalt , and Nickel powders with different particle sizes were subjected to sieving and He-Ne laser system to determine the particle size .

1wt% from each powders was blended carefully with 99wt % from Iraqi oil .

Microscopic examination were carried for all samples to reveal the particle size distribution .

A Siemens type SRS sequential wavelength dispersive(WDS) X-ray spectrometer was used to analyze all samples, and the XRF intensity were determined experimentally and theoretically for all suspended samples , Good agreement between theoretical and experimental results were found .
