Abstract A new group of materials called the silicon lanthanide oxynitrides has been prepared by the reaction between Si3N4 and several oxides of the lanthanide series (La2O3, Sm2O3, Dy2O3, Er2O3, and Yb2O3). These oxides formed compounds of the type Si3N4 · R2O3 and R4Si2O7N2 (R being lanthanide). In addition La2O3 and Yb2O3 formed the compounds 2Si3N4 · La2O3 and Yb2Si3O5N2, respectively. Certain similarities in the unit cells of these compounds have been noted, and their structures are discussed in terms of similarity to known minerals. It is suggested that this group of materials contains a large number of compounds.
