Praseodymium (III,IV) Oxide
Praseodymium (III,IV) Oxideshi ne mahaɗan inorganic tare da dabarar Pr6O11 wanda ba ya narkewa a cikin ruwa. Yana da tsarin fluorite mai siffar sukari. Shi ne mafi kwanciyar hankali nau'i na praseodymium oxide a yanayi zafin jiki da kuma matsa lamba.It ne mai matuƙar insoluble thermally barga Praseodymium tushen dace da gilashin, gani da yumbu aikace-aikace. Praseodymium(III,IV) Oxide gabaɗaya Babban Tsafta ne (99.999%) Praseodymium(III,IV) Oxide (Pr2O3) Foda yana samuwa a cikin mafi yawan kundin. Maɗaukakin tsafta mai ƙarfi da ƙaƙƙarfan tsafta yana haɓaka ingancin gani da fa'ida a matsayin ma'aunin kimiyya. Nanoscale foda da kuma dakatarwa, azaman madadin babban yanki mai tsayi, ana iya la'akari da shi.
