High Pressure Synthesis of New Silicon Sulfides

Abstract : By heating mixtures of silicon and sulfur in various atomic ratios to temperatures of 700-2300 degrees C at pressures of 25-80 kilobars (kb), a variety of reaction products has been obtained. In addition to the previously known SiS2 and SiS, these include several colored glasses and three new crystalline materials with distinctive X-ray diffraction patterns.
