Title
(EN) COMPOSITE ELECTROCONDUCTING MATERIAL
(FR) CORPS COMPOSITE ELECTROCONDUCTEUR
Abstract
(EN)
A composite electroconducting material that can be used as electrothermal element in a wide range of applications, without affecting its physical characteristics because of high temperatures and operative conditions, comprises quick cement as binder, colloidal graphite as electroconducting component and an antiplastic substance, e.g., chamotte, diabase, quartz sand or mixtures thereof, as thermally stable filler.
(FR)
L'invention concerne un corps composite électroconducteur pouvant faire office d'élément thermique dans de nombreuses applications, et ce sans pour autant que ses caractéristiques physiques ne soient altérées par les températures élevées et les conditions de fonctionnement. Ce corps renferme du ciment à prise rapide comme liant, du graphite colloïdal comme constituant électroconducteur, et une substance antiplastique, par exemple la chamotte, la diabase, le sable quartzeux ou des mélanges de ceux-ci, comme matière de charge thermiquement stable.
