Significance and Use

These test methods provide a practical way to measure the concentration of certain trace elements in graphite. Many end uses of graphite require that it be free of elements which may be incompatible with certain nuclear applications. Other elemental contamination can affect the rate of oxidative degradation.

These test methods allow measurement of trace amounts of contaminants with a minimal amount of costly equipment. The colorimetric procedures used are accessible to most laboratories.


1.1 These test methods cover the chemical analysis of graphite.

1.2 The analytical procedures appear in the following order:

Silicon by the Molybdenum Blue (Colorimetric) Test Method8 to 14
Iron by the o-Phenanthroline (Colorimetric) Test Method 15 to 21
Calcium by the Permanganate (Colorimetric) Test Method22 to 28
Aluminum by the 2-Quinizarin Sulfonic Acid Test Method29 to 35
Titanium by the Peroxide (Colorimetric) Test Method 36 to 43
Vanadium by the 3,3`-Dimethylnaphthidine (Colorimetric) Test Method 44 to 51
Boron by the Curcumin-Oxalic Acid (Colorimetric) Test Method52 to 59

1.3 The preferred concentration of sought element in the final solution, the limits of sensitivity, and the precision of the results are given in Table 1.

1.4 The values stated in SI units are to be regarded as the standard.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. See 56.1 for specific caution statement.
