砷钇矿是一种罕见的稀土砷酸盐矿物。与氟碳钙钇矿,磷钇矿、钍石、铌铁矿等共生。其分子式为Y(AsO_4)。在系统分析中主要测定TR_2O_3,As_2O_3,SiO_2,P_2O_8,Fe_2O_3,CaO,MgO,Al_2O_3,V_2O_5,ThO_2,U_3O_8,MnO等成份。砷钇矿的研究对成矿条件,稀土和砷的地球化学研究都是很有意义的。 砷钇矿中砷和稀土是主要成份。二氧化硅含8％左右,还有少量的磷和钒等其他元素。砷,磷,硅在测定时相互干扰严重。稀土,砷影响钒,铝的测定。
Arsenite is a rare rare earth arsenate mineral. With the fluorocarbon-yttrium ore, xenotime ore, thorium, niobium iron ore and other symbiosis. Its formula is Y (AsO_4). The major components of TR_2O_3, As_2O_3, SiO_2, P_2O_8, Fe_2O_3, CaO, MgO, Al_2O_3, V_2O_5, ThO_2, U_3O_8 and MnO were determined in the system analysis. The study of arsenic yttrium is of great significance for the study of metallogenic conditions, the geochemistry of rare earth and arsenic. Arsenic and rare earth arsenic yttrium is the main ingredient. Silicon dioxide contains about 8%, there are a small amount of other elements such as phosphorus and vanadium. Arsenic, phosphorus, silicon in the determination of mutual interference serious. Rare earth, arsenic affect the determination of vanadium, aluminum.
