About this book
Melting points of the iron group elements by a new radiation method
Year: 1907
The method used consists in heating a small quantity of the metal whose melting-point is to be observed on a platinum strip through which a current is passed. This is surrounded by a blackened brass tube with a mica window, and the sample is simultaneously watched by two observers through a microscope and an optical pyrometer. In the calibration of the optical pyrometer 1,753 degrees was taken as the Pt melting-point. The correction for absorption and reflection by the mica is about 15 degrees , and the correction for the selective emission of Pt for the light used - in this case red, lambda = 0.66 mu - is
