【 摘 要 】

Several metals systems were reviewed for their potential to act as resistive temperature devices. Platinum metal was selected as the metal of choice. Platinum was plated onto 5 mil copper wire, and then subsequently coated with Accusol's proprietary ceramic coating. The copper was etched out in an attempt to make a pure platinum, high resistive, resistive-temperature device. The platinum plating on the wire cracked during processing, resulting in a discontinuous layer of platinum, and the element could not be formed in this way.
