This standard specifies a method for the determination of calcium content in molybdenum and its products, applicable to the range of 0.0005% to 0.030%. Absorbance of calcium is measured by flame atomic absorption spectroscopy (AAS) by analyzing samples in muriatic acid medium using hydrogen peroxide and citric acid. This method provides an accurate means of analyzing calcium content in molybdenum materials and is suitable for quality control and composition analysis.
