Evaluating the presence of titanium in XIX-century Brazilian steels by energy-dipersive X-ray fluorescence

Abstract:

Ore, pig , iron and steel pieces from the XI Century iroworks Royal St. John of Ipanema Iron Foundry (Real Fábrica de Ferro São João de Ipanema), in Iperó, Brazil, were analyzed by Energy-Dispersive X-Ray Fluorescence (EDXRF) spectroscopy, with the aim of investigating the presence of deleterious elements as Ti and P the minerals and the resulting products. Analytical modifications made in order to improve the detection limits for Ti and P are discussed. Both elements were found in the raw material and in the products, but large differences in chemical composition were found in different sample or regions of samples.
