Zinc phosphide (Zn 3 P 2) is an inorganic chemical compound.It is a grey solid, although commercial samples are often dark or even black. It is used as a rodenticide. [5] Zn 3 P 2 is a II-V semiconductor with a direct band gap of 1.5 eV [6] and may have applications in photovoltaic cells. [7]
Zinc diphosphide (Zn P 2) is an inorganic chemical compound. It is a red semiconductor solid with a band gap of 2.1 eV. [2] It is one of the two compounds in the zinc-phosphorus system, the other being zinc phosphide (Zn 3 P 2).

Zinc phosphate is an inorganic compound with the formula Zn 3 (PO 4) 2. This white powder is widely used as a corrosion resistant coating on metal surfaces either as part of an electroplating process or applied as a primer pigment (see also red lead). It has largely displaced toxic materials based on lead or chromium, and by 2006 it had become ...
In chemistry, a phosphide is a compound containing the P 3− ion or its equivalent. Many different phosphides are known, with widely differing structures. [ 1 ] Most commonly encountered on the binary phosphides, i.e. those materials consisting only of phosphorus and a less electronegative element.
Zinc compounds are chemical compounds containing the element zinc which is a member of the group 12 of the periodic table. The oxidation state of zinc in most compounds is the group oxidation state of +2. Zinc may be classified as a post-transition main group element with zinc(II). Zinc compounds are noteworthy for their nondescript appearance ...
Phosphine is an attractive fumigant because it is lethal to insects and rodents, but degrades to phosphoric acid, which is non-toxic. As sources of phosphine, for farm use, pellets of aluminium phosphide (AlP), calcium phosphide (Ca 3 P 2), or zinc phosphide (Zn 3 P 2) are used. These phosphides release phosphine upon contact with atmospheric ...
Dithiophosphate has the formula [PO 2 S 2] 3−, which has C 2v symmetry. Sodium dithiophosphate, which is colorless, is the major product from the reaction of phosphorus pentasulfide with NaOH: [6] P 2 S 5 + 6 NaOH → 2 Na 3 PO 2 S 2 + H 2 S + 2 H 2 O. Dithiophosphoric acid is obtained by treatment of barium dithiophosphate with sulfuric acid:
