After completing his graduate studies, Dr. Kreidler spent thirteen years with the General Electric Co. at the Nela Park Research Laboratory in Cleveland, Ohio. While at G. E., he conducted basic and applied research on luminescent materials, thermionic emission materials, and the interactions between ceramic materials and low pressure gas discharges. He joined Ohio State's Ceramic Engineering Department in 1980.

Dr. Kreidler is expert in the subject of phase equilibrium and has published a number of original phase diagrams. He uses phase diagrams as a guide in the processing of new ceramic materials and as an aid in understanding their properties. For example, the Nd2O3-P2O5 (at right) and La2O3-P2O5 phase diagrams were developed in a search for new luminescent materials. Since publication of the La2O3-P2O5 diagram, LaPO4 has been developed into an important commercial phosphor.

Other research areas he has beeninvolved in since joining Ohio State include:

  • interaction of phosphors with atomic hydrogen;
  • thermal conductivity of ceramic powders;
  • electronic and ionic conduction in a variety of oxide materials;
  • processing of high temperature superconductors;
  • processing of cellular structure ceramics;
  • oxygen sensors;
  • hot gas corrosion of SiC and Si3N4 ceramics;
  • percolation effects in random three dimensional composites.

His current work includes:

  • synthesis and characterization of phosphors for use in fluorescent lamps
  • development of methods for coating ceramic insulators onto wires for high temperature instrumentation in advanced jet engines
  • chemical methods for improved synthesis of doped bismuth oxide powders. These powders are to be used as electrolytes in fuel cells and also in small oxygen generators for patients with lung disorders who must breathe pure oxygen.

Dr. Kreidler has served as:

  • Associate Editor, Journal of the American Ceramic Society, 1988-1993
  • Editorial Subchairman for the same journal, 1974-1979
  • Contributing Editor, Phase Diagrams for Ceramists, 1981- 1990
  • Contributing Editor, Communications of the American Ceramic Society, 1981-1983.

He has held all offices of the Central Ohio Section of the American Ceramic Society and served as Chairman in 1984 and 1998. Dr. Kreidler has been responsible for introducing computer data acquisition into the Department's undergraduate laboratories. He has advised seven Ph.D. and 13 M.S. students, published 23 papers, and holds one patent.
