Phenakit-Mischphasen mit Zn2SiO4 als Wirt

The compounds cristallizing in the phenakite type are summarized. Into these compounds (especially Zn₂SiO₄), their isotypic mixed phases or their homotypic mixed phases with olivine type compounds or tetrafluorometallates(II) retaining the phenakite structure a large number of oxides or fluorides may be inserted forming heterotypic mixed phases without change of the lattice type. The results are summarized for the different sites and those elements which may be inserted. The spectral remission for some coloured pigments of phenakite mixed phases with Zn₂SiO₄ is reported.
