摘要：

The reduction of WO3 by elemental phosphorus at 800-degrees-C leads to the formation of several products. Depending on the molar ratio n(P):n(WO3) in the course of this investigation, WP, WP2, WPO5 and, for the first time, tungsten(IV) diphosphate, WP2O7, were prepared. By chemical vapour transport reactions (transport agent iodine; 200 mg per ampoule; 1050 --> 950-degrees-C), the phosphides and phosphates of tungsten can be purified and crystallized. Heterogeneous and homogeneous equilibria, responsible for the vapour-phase transport of the tungsten compounds, will be discussed.
