Determination of the phosphorus content in cast iron brakeblocks by chemical methods (TM-MS-61)

Previous analysis on standard and high phosphorus cast iron was carried out by an X-ray fluorescence method (X.R.F.) This analysis suggested no segregation in blocks. However, later some inconsistency emerged between wet chemical methods and X.R.F. during the analysis of special casts of high phosphorus blocks, prepared by B.C.I.R.A. and...
