碳化钛粉中总碳、游离碳的测定

Determination of Total Carbon and Free Carbon in Titanium Carbide Powder

摘要:

采用化学分离与高频红外吸收碳硫分析仪相结合测定碳化钛粉中的总碳、游离碳，成功地解决了传统的重量法对于低含量碳测定存在较大的误差缺陷，同时使测定时间上大大缩短。该方法的准确性高，分析结果重现性好，同时也扩大了高频红外吸收碳硫分析仪的适用范围。

Abstract:

The chemical separation and HF infrared absorption C/S instrument were used to determine total carbon and free carbon in titanium carbide powder. It is successful to solve the major fault of the traditional gravimetric method in determining lower carbon, and short the determination time. The method has high accuracy and the analytical results have good reproducibility. Meantime it also develops the applicable rang of HF infrared absorption C/S instrument.
