Spectrographic Determination of Boron and Silicon in Low-Alloy Steel by Fluoride Evolution

Abstract

Concentrations are determined in the following sequence:The iron concentration is read directly from the applicable calibration curve. 24 (1954).

Determination of Micro Quantities of Boron in Steel by Solvent Extraction Method

“…If both soluble and insoluble boron are to be determined, follow the procedure as before, but when transferring the solution to the polyethylene graduate, filter the solution through a small S. & S. 589 Blue Ribbon filter paper using a polyethylene funnel and wash it with as little water as possible (ca. 4…”
