Sorbents in treatment of uremia: A short history and a great future. The virtual identity of atomic and ionic sizes, resulting from the lanthanoid contraction, has the effect of making the chemical behaviour of these two elements more similar than for any other pair of elements known. This film protects the metal from further corrosion (rusting). Hydrides The term hydride is used to indicate compounds of the type M x H y and not necessarily to indicate that any compounds listed behave as hydrides chemically. The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. Its chemical formula is ZrSiO4. At normal temperatures it is not particularly reactive but becomes quite reactive with a variety of nonmetals at elevated temperatures. Zirconium compounds are also used in TiO 2 … Zirconium sulfate is also obtained as a white crystalline tetrahydrate, ZrSO4.4H2O.
