Abstract

The determination of combined carbon in cast iron may be completed absorptiometrically since Beer's Law is obeyed. As the intensity of colour produced by a given sample varies with conditions, e.g., acid concentration and time of heating the solution, a standard must be included in each batch of determinations. The optimum conditions for colour development are noted. Colour stability is good.

## Abstract The EBIC data obtained from individual edge and Frank partial dislocations ^i^n Si, and described in other publications, are related to defect parameters, such as the capture cross‐section for minority carriers, which determine electrical recombination properties of dislocations. A two
