Zusammenfassung: | A current-conducting film for electric resistance heaters, consisting of tin dioxide, antimony and boron which are used in the following ratios in percent by weight: tin dioxide 78.0-96.8; antimony, 3.0-20.0 boron, 0.2-2.0. The current conducting film exhibits high thermal stability (up to 900 DEG C. in air), critical specific input of 60 W/cm2 with strong adhesion to a support and good reproducibility of electrical parameters and physical properties. |
