In this paper we examine critically when the term diffusion is an appropriate description of the transport processes occurring in steady state active plasmas. It is suggested that ambipolar flow is a more correct and general expression. The paper examines in detail the situations in: (a) conventional active low temperature electropositive plasmas generated by electron impact such as the positive column of a d.c. gas discharge; (b) such plasmas where the electrons are magnetized and the ions not; (c) electronegative plasmas such as those used in plasma processing where there is separation into an ion–ion core and an outer electron–ion plasma.
