Phosphine selected metal phosphides

Related questions
Can metal phosphides be synthesized from elemental phosphorus? In principle, all metal phosphides and polyphosphides can be synthesized from elemental phosphorus and the respective metal element in stoichiometric forms. However, the synthesis is complicated due to several problems. The exothermic reactions are often explosive due to local overheating.
Where should a phosphine safety card be displayed? INTERNATIONAL CHEMICAL SAFETY CARD This card should be easily available to all health workers concerned with, and users of, phosphine and metal phosphides. It should be displayed at, or near, entrances to areas where there is potential exposure to phosphine or phosphides, and on processing equipment and containers.
Why is phosphine considered a gaseous form of phosphorus? Perhaps because of its strong association with elemental phosphorus, phosphine was once regarded as a gaseous form of the element, but Lavoisier (1789) recognised it as a combination of phosphorus with hydrogen and described it as phosphure d'hydrogène (phosphide of hydrogen). [NB 2]
What is an example of a group 1 phosphide? An example of a group 1 phosphide is sodium phosphide ( Na3P ). Other notable examples include aluminium phosphide ( AlP) and calcium phosphide ( Ca3P2 ), which are used as pesticides, exploiting their tendency to release toxic phosphine upon hydrolysis. Magnesium phosphide ( Mg3P2) also is moisture sensitive.
