Thank you for sending us SN/T 0256-93.
1. In 4.2 in SN/T 0256-93, a method of processing SiC to determine the content value of SiC is described as the second method.
When you measure Fe2O3 in SiC, do you use the process described in 4.2 in SN/T 0256-93 or a part of 4.2?
Please confirm whether 4.2 in SN/T 0256-93 has any relevance to the analysis of Fe2O3 in SiC or not.
2. Is a method for processing SiC to determine Fe2O3 described in GB/T 3045-2003?
3. Would it be possible for you to send us the description of GB/T 3045-2003 related to the process of SiC to measure Fe2O3 and measurement method to determine Fe2O3?
4. Could you be so kind as to let us know the outline of pre-processing method when you analyze Fe2O3 if GB/T 3045-2003 does not mention about the pre-processing method of SiC to analyze Fe2O3?
