摘要：
An electronic smoking article is disclosed. The article includes a coil heater (14) and a wick (28). The coil heater is located in an inner tube of the article, the wick in communication with a liquid to be vaporised. The coil heater is formed of an iron-free, nickel-chromium alloy and has substantially uniformly spaced windings (111). It is known that heating glycerin and/or propylene glycol beyond certain temperatures produces carbonyls (which include formaldehydes). Iron oxide tends to catalyse these reactions such that carbonyls are produced at lower temperatures. By using alloys essentially free of iron content, such catalysation is avoided and the possibility of producing carbonyls and other constituents is minimized.
