Optical Properties of Coals and Graphite

James Thomas McCartney, S. Ergun

Open publisher page 15 citations

Abstract

From Abstract: Optical Properties of U.S. coals of differing rank have been investigated by the Bureau of Mines for about 20 years. These investigations have been made to further the development of an objective basis for petrographic analysis of coal and to add knowledge of the structure and composition of coal and coal components by determining their optical constants in various regions of electromagnetic spectrum.
