Dr. Robert S. Roth

Dr. Roth is a Scientist Emeritus with the National Institute of Standards and Technology (NIST) (formerly NBS, The National Bureau of Standards) in Gaithersburg, MD.

Dr. Roth received a B.A. in Geology from Coe College in Cedar Rapids, IA in 1947 and M.S. and Ph.D. degrees in Geology from the University of Illinois in 1950 and 1951. Before arriving at NBS in 1951, Bob worked as a field assistant for the U.S. Geological Survey and as a Research Associate at the Univ. of Illinois Engineering Experimental Station. While at NIST he became Chief of the Solid State Chemistry Section in the Ceramics Division of what is now the Materials Science and Engineering Laboratory. Bob is a prolific publisher of manuscripts describing phase equilibria, crystal chemistry, and crystal structure analyses, and has authored or coauthored over 225 technical papers. He is considered the world’s leader in the phase equilibria and crystal chemistry of ceramic oxides. He received both the Silver and Gold medals from the U.S. Dept. of Commerce for distinguished achievement in the federal service. Bob also received the Wilhelm R. Buessem award from the Center for Dielectric Studies, and is a fellow of both the Geological and Mineralogical Societies of America. In 2003 he achieved recognition as an ISI “Most Highly Cited” author, one of only three scientists from NIST with this distinction.

Bob Roth is a Fellow and Emeritus Member of The American Ceramic Society and is a member of the Basic Science Division. He was the Sosman Memorial Lecturer in 1991 and also the recipient of the John Jeppson Award (1995) and the Spriggs Phase Equilibria Award (2003). He joined the Society in 1959, has been a reviewer for the Journal of The American Ceramic Society since 1960, and served as an associate editor from 1989-2005. Bob served as a member of the Publications Committee (1979-1980) and is an ad-hoc member of the Phase Equilibria Program committee (1980-present). Since 1980, Bob has been the Senior Editor of the volumes published by The American Ceramic Society entitled “Phase Equilibrium Diagrams” (formerly “Phase Diagrams for Ceramists”), which have provided an enormous benefit for the global ceramics community.
