Application of the Interference Method to the Determination of the Surface Area of Metallic Nickel Films

Abstract

WITH the quantitative establishment of the interference theory of the production of colours on metallic copper (Proc. Roy. Soc., A, vol. 1 15, p. 570; 1927) and its application to the study of the sintering of reduced copper films by heat treatment (Jour. Chem. Soc., July, p. 1597; I927) the behaviour of nickel films becomes of increasing interest. Spectrophotometric observations on the growth of oxide films on nickel showed again that interference was the primary cause of the colours developed during oxidation, and hence the same method is applicable to the study of nickel films. Moreover, the dispersion shown by nickelous oxide is very much smaller than that shown by copper oxide.
