Abstract
Abstract The interaction of tetraethyl‐lead vapour and gaseous hydrogen telluride has been investigated and the conditions found under which lead telluride mirrors can be formed. A reaction mechanism is postulated to account for the by‐products obtained. A range of conditions has been found over which lead and tellurium mirrors may be formed individually from the vapours on a mica substrate. The preparation of hydrogen telluride by a lithium aluminium hydride reaction was not very satisfactory owing to the unstable nature of the gas.
