元素磷有二种形式:红磷和黄磷。红磷不挥发,不溶、毒性小。黄磷(或白磷)极易氧化,在常温中自燃,它是磷矿石与焦炭、石英在高温下还原制得的,是制红磷、焰火、照明弹和有机磷杀虫剂的原料。由于啮齿动物对杀鼠灵(即丙酮香豆素衍生物)的抵抗力日益增加,含磷杀鼠药应用得更为广泛,国外各种商品磷化锌杀鼠药含黄磷2～5%。
Elemental phosphorus has two forms: red phosphorus and yellow phosphorus. Red phosphorus is not volatile, insoluble, less toxic. Phosphorus (or white phosphorus) easily oxidized, spontaneous combustion at room temperature, it is phosphate rock and coke, quartz reduction obtained at high temperatures, is made of red phosphorus, fireworks, flares and organophosphate insecticide raw materials. As rodents on warfarin (ie, acetone coumarin derivatives) increasing resistance, anti-rodent drugs phosphorus is more widely used, foreign products zinc phosphide anti-rat drugs containing yellow phosphorus 2 to 5% .
