| Abstract: | In order to meet the requirement for analysis of silicon carbide in the deoxidizer used for steel-making, a new infrared absorption method was established based on the national standard methods and through testing Loss-on-ignition, selecting flux, assessing linearization, and testing precision and accuracy. The recovery of the method is more than 98% with the relative standard deviation of 0.5% to 0.7%, indicating high accuracy, minor error and big practicality of the method. |
