磷在地壳中广泛存在,约占地球重量的0.08％。自然界中磷主要呈化合物状态,目前已发现的磷矿物约有190种,最常见的是磷灰石、磷钙石、兰铁矿、独居石、磷钇矿。铁陨石中磷的含量在0.02—0.94％之间,磷的存在形式主要为磷酸盐。月岩中的P_2O_5为0.2—1.5％。
Phosphorus is widespread in the earth’s crust, accounting for about 0.08% of Earth’s weight. In nature, phosphorus is mainly in the form of a compound. About 190 kinds of phosphorus minerals have been discovered so far. The most common ones are apatite, phosphorite, iron ore, monazite and xenotime. The content of phosphorus in iron meteorites is between 0.02-0.94%, and the main form of phosphorus is phosphate. P_2O_5 in lunar rocks is 0.2-1.5%.
