The invention belongs to an alloy trace element analysis technology and relates to a method for measuring the sulfur content in a powdered high-temperature alloy. In the method, the sulfur content is measured by adopting a high-frequency infrared carbon and sulfur analyzer and a high-frequency induction combustion-infrared ray absorption method. The measurement method comprises the following steps of: measuring a sulfur content blank value; preparing a sulfur correction sample; correcting by adopting the high-frequency infrared carbon and sulfur analyzer; sampling and preparing a sample; preparing a specimen; and measuring the sulfur content in the high-temperature alloy powder sample to be measured. The invention improves the accuracy of a measuring result, solves the measuring problem of the sulfur content in the powdered high-temperature alloy and provides a reliable technical guarantee for the development, the smelting, the application and the quality control of the powdered high-temperature alloy.
