01 / Technical dossier
The material. The evidence.
Reference properties and the analytical work needed to assess this material for industrial use.
TO-REF-MONAZITE
Revision 1.0 · Technical reference
Material identity
(Ce,La,Nd,Th)PO₄ (representative)
Rare-earth phosphate group. Composition and thorium content vary; it is not interchangeable with every rare-earth ore or clay.
