Abstract
An electrically-conductive fine particle powder comprises fine, hollow spherical particles of non-magnetic material such as glass or resin plated with a metal and having a bulk density of 0.2 to below 0.9 g/cm.sup.3. An exothermic electrically-conductive coating or paste comprises the above powder and a synthetic resin binder. An electrically-conductive heating unit is formed from a suitably shaped solid or solid surface coated or impregnated with the above coating or paste and is operable at low voltages.
