|Section2= |Section3= |Section7= }} Zinc phosphide (Zn3P2) is the inorganic chemical compound. It is a grey solid, although commercial samples are often dark or even black. It is used as a rodenticide. Zn3P2 is a semiconductor with a direct band gap of 1.5 eV. and may have applications in photovoltaic cells.〔Specialist Periodical Reports, Photochemistry, 1981, Royal Society of Chemistry, ISBN 9780851860954〕 A second zinc phosphide is known, with the stoichiometry ZnP2. ==Synthesis and reactions== Zinc phosphide can be prepared by the reaction of zinc with phosphorus; however, for critical applications, additional processing to remove arsenic compounds may be needed.〔F. Wagenknecht and R. Juza "Zinc Phosphides" in Handbook of Preparative Inorganic Chemistry, 2nd Ed. Edited by G. Brauer, Academic Press, 1963, NY. Vol. 1. p. 1080-1.〕 :3 Zn + 2 P → Zn3P2 Another method of preparation include reacting tri-n-octylphosphine with dimethylzinc. Zinc phosphide reacts with water to produce phosphine (PH3) and zinc hydroxide (Zn(OH)2): :Zn3P2 + 6 H2O → 2 PH3 + 3 Zn(OH)2 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「zinc phosphide」の詳細全文を読む スポンサード リンク
