What is the matter with the gray-white substance found on the crucible cover after measuring the volatile matter?
The gray-white substance on the XRF fusion machine crucible cover is generated by the oxidation of the coal body, which will make the volatile matter measurement value higher. This oxidation phenomenon is caused by the crucible cover not being tight and air invading the Automatic Fusion Machine for XRF crucible.
For bituminous coal, especially high-volatile coal, it is not serious, because a large amount of volatile matter will escape to prevent air from invading. For low-volatile substances such as coke and anthracite, the oxidation effect may be more serious. Therefore, a few drops of volatile liquids such as benzene can be added to the coal sample. When heated, the volatile liquid evaporates and escapes from the Sample-melting Furnace for X-ray fluorescence Analysis crucible, thereby preventing air from invading.
