Abstract
Conditions are given, which permit a significant reduction in the time required for the synthesis of iron and nickel phosphorotrisulfides in ampules. The electrical conductance of pressed polycrystalline sample s of these compounds was studied at 25-400-degrees-C. Nickel phosphoro trisulfide is an intrinsic semiconductor, while FePS3 is an extrinsic semiconductor. The finding of a region of extrinsic conductance for Fe PS3 is related to its characteristic slight deviation from stoichiomet ric composition.
