【Abstract】 High frequency infrared absorption spectroscopy was used to determine the content of carbon in tantalum powder, niobium powder and tantelum carbide. The flux, the sample mass and the flow of oxygen were studied. Without determining S, when Cu and W are used as the flux, the sample mass is 0.5 g and the flow of oxygen is 2 L/min, the results meet the analysis requirements.更多还原
