A Process Of Estimation Of Oxygen Content In Copper By Metallographic Method
Abstract: The present invention relates to proposes a method for developing the alternate methodology via metallography comprising of collecting and banking of different grades of copper samples having varied range of oxygen content; testing Oxygen content by spectroscopy; Collecting and banking of samples of oxygen content of from 1 PPM to 1000 PPM; preparing metallographic samples for each sample tested for oxygen content using spectroscopy; capturing the metallographic images at fixed magnification for each samples; preparing metallographic Atlas of copper samples having different level of oxygen content; Assessing/ Estimating, by comparison method, of oxygen content of an unknown samples can be qualitatively possible and also quantitatively near approximation of the oxygen content in shortest possible time.
