I am trying to modify a hot-wire cell for thermal conductivity measurement so that electricall conducting materials can be studied. The materials (powders, fluids,..) surround a thin platinum wire. This technique is widely used to measure the thermal properties of insulating materials. The problem is that I am using a 25.4 microns bare Pt wire. The resistance of the Pt wire (from which the temperature is found) will be affected by the electrically conducting material depending on the conductivity of the later. I am looking for a high temperature (above 500 C) electrically insulating paint that I can use (either by spraying or brushing) to insulate the wire from the surrounding medium. Any suggestions are appreciated. ---------------------------------------------------------- A. Outzourhit e-mail: aoutzour@slate.mines.colorado.edu Tel: (303) 273-3832
