NdPr oxide is the non-separated oxide of neodymium and praseodymium.

It is together with terbium and dysprosium the raw material for neodymium-iron-boron (NdFeB) permanent magnets.

Typically an NdFeB magnet would contain ca. 27% NdPr, ~1% dysprosium, ~1% terbium, ~1% boron and ~70% iron oxide (magnetide).
