Abstract
According to the invention there is provided an electrothermic composition comprising: a carbon component; a graphite component having a crystallinity of 99.9% and wherein the graphite is heat treated at a temperature of 2500° C. to 3000° C., and a binder, whereby the composition has a thermal coefficient of electrical resistance (TCR) of ±0.0001 to 0.0010 per ° C. over a temperature range of from about 20° C. to 60° C. in an airborne environment, wherein the ratio of the first conductive component and the second resistor component is selected between 10:1 to 1:10.
