• Zemannite - Wikipedia

    en.wikipedia.org/wiki/Zemannite Zemannite is a very rare oxide mineral with the chemical formula Mg 0.5 ZnFe 3+ [TeO 3] 3 ·4.5H 2 O. It crystallizes in the hexagonal crystal system and forms small prismatic brown crystals.Because of the rarity and small crystal size, zemannite has no applications and serves as a collector's item.

The chemical composition of zemannite was analysed by EMPA and by ICP-AES, showing conclusively that zemannite contains negligible Na, though the presence of Na should always be ...
