CHARACTERISTICS OF METAL VAPORS.

Abstract

The objective of this experimental and analytical study is to determine the effects of metal vapors on the radiation heat transfer characteristics of arc and plasma systems. A high temperature absorption cell suitable for transmission measurements of alkali metal vapors at temperatures of 300 to 750C with vapor path lengths of 4 to 8 inches is described. The results of calibration tests using the absorption cell and an optical system capable of resolution of 1 to 8 A over the spectral region from 2000 to 9000 A are presented. Typical data on the transmission of sodium vapor are given, and methods of data reduction to obtain spectral absorption coefficients are proposed. A preliminary discussion of the radiation characteristics of vaporized electrode components such as tungsten, copper, and graphite is given. (Author)
