Abstract

In the course of work, on the CaO-Nb205-Si02 System, a series of compositions on the Ca0-Nb2-05 binary join has been studied. There are indications of the existence of three calcium niobates. These compounds have been characterized by X-ray powder diffraction and optical data. Single crystal studies have given information concerning the crystallography of these materials.
