A method for synthesizing and single crystal growth of silver gallium arsenide (SSPG) polycrystalline raw materials for infrared non - linear optical materials was reported. The temperature swing synthesis of gas phase transport in two temperature zones and the method of growth - reduction by crucible rotation were reported. The AgGaS2 polycrystalline material with high purity and single phase density was synthesized, and AgGaS2 single crystal ingot with size of φ15mm × 30mm was grown. The structural integrity of the crystal was analyzed. It was observed that the six-step X-ray diffraction peak of the AgGaS2 {011} family of anomalies exhibited an anomalous enhancement of higher-order diffraction intensities. The crystal dislocation pits were observed by scanning electron microscopy (SEM).
