ZnP 2 has a room-temperature tetragonal form that converts to a monoclinic form at around 990 °C. [3] In both of these forms, there are chains of P atoms, helical in the tetragonal, semi-spiral in the monoclinic. [4] This compound is part of the Zn-Cd-P-As quaternary system and exhibit partial solid-solution with other binary compounds of the ...
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 pyrophosphate can be obtained from the thermal decomposition of zinc ammonium phosphate. [2]2 ZnNH 4 PO 4 → Zn 2 P 2 O 7 + 2 NH 3 + H 2 O. It can also be obtained from the reaction between sodium carbonate, zinc oxide, and ammonium dihydrogen phosphate.
Use of zinc pyrithione is prohibited within cosmetic products in the European Union since December 2021. [19] The substance was considered safe for use in rinse-off and leave-in products of different tested concentrations, but due to potential environmental toxicity consideration of the use of zinc pyrithione was made against potential ...
The [BAr F 4] − anion with four fluorinated aryl groups distributed tetrahedrally about a central boron atom. Tetrakis[3,5-bis(trifluoromethyl)phenyl]borate is an anion with chemical formula [{3,5-(CF 3) 2 C 6 H 3} 4 B] −, which is commonly abbreviated as [BAr F 4] −, indicating the presence of fluorinated aryl (Ar F) groups.
Zinc oxide, ZnO, is the most important manufactured compound of zinc, with a wide variety of uses. [2] It crystallizes with the Wurtzite structure. It is amphoteric, dissolving in acids to give the aqueous Zn 2+ ion and in alkali to give the zincate (a.k.a. tetrahydroxozincate) ion, [Zn(OH) 4] 2−. Zinc hydroxide, Zn(OH) 2 is also amphoteric.
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).
Structure of a monomeric zinc dialkyldithiophosphate. Zinc dialkyldithiophosphates (often referred to as ZDDP) are a family of coordination compounds developed in the 1940s that feature zinc bound to the anion of a dialkyldithiophosphoric salt (e.g., ammonium diethyl dithiophosphate). [1]
