- Analysis of Free Carbon in SiC - Horiba
Free carbon in SiC can be quantitatively analyzed safely in a short time compared with the traditional method using hydrofluoric acid It shows good performance for samples with slow combustion such as free carbon using HORIBA's unique combustion gas collection mechanism, compared with conventional instruments
- ISO 21068-1 - iTeh Standards
ISO 21068, Parts 1 to 3, provide analytical methods for the determination of free carbon, and SiC in the presence of oxidic compounds in particular SiO 2 Because of the diversity of laboratory equipment, the three parts of ISO 21068 summarize broadly used
