Product description
Natural forms of zinc phosphate include
minerals hopeite and parahopeite, Zn3(PO4)2•4H2O. A somewhat similar mineral is
natural hydrous zinc phosphate called tarbuttite, Zn2(PO4)(OH). Both are known
from oxidation zones of Zn ore beds and were formed through oxidation of
sphalerite by the presence of phosphate-rich solutions. The anhydrous form has
not yet been found naturally
