Nitrido Zeolites. A Novel and Promising Class of Compounds.
10th International Zeolite Conference, July 17 - 22, 1994, Garmisch-Partenkirchen, Germany.
The synthetic approach to nitrido zeolites has been opened up by the synthesis
and characterization of the P-N-sodalite class of compounds. A variety of
compounds with a general formula M7_xH2 x[P1 2N24]X2-y with Μ = Zn2 + , Co2 + , Ni2 + etc.
and X = F", CI", Br", Γ has been obtained. Striking features of these compounds are
high chemical and thermal stability as well as an intense colour in some cases.
