SYNTHESIS OF POLYCRYSTALLINE CdSi[P.sub.2] IN A GRADIENT TEMPERATURE FIELD

A procedure for the synthesis of a CdSi[P.sub.2] compound from the initial elementary components in a gradient thermal field has been developed. The phase and chemical composition of the synthesized and recrystallized material is confirmed by the data of X-ray diffraction analysis and scanning electron microscopy with an energy-dispersive system. The polycrystalline material obtained by the developed method will be used to grow bulk nonlinear optical CdSi[P.sub.2] crystals. Keywords: nonlinear optical crystal, CdSi[P.sub.2], synthesis, polycrystal.
