The rare earth salts (hydrates, nitrates, acetates, oxalates, carbonates, and chlorides) are tailored for our customer’s requirements and are known for the extraordinary purity control of transition metals and halogen group elements.? For the rare earth oxides, in addition to the superior purity control, PIDC also specializes in porosity and particle size control, tailoring these physical properties to achieve enhanced performance in the intended applications.
