ASTM C809
1. Scope
1.1 These test methods cover procedures for the chemical, mass spectrometric, and spectrochemical analysis of nuclear-grade aluminum oxide and aluminum oxide-boron carbide composite pellets to determine compliance with specifications.
1.2 The analytical procedures appear in the following order:
| Sections | |
| Boron by Titrimetry | 7 to 13 |
| Separation of Boron for Mass Spectrometry | 14 to 19 |
| Isotopic Composition by Mass Spectrometry | 20 to 23 |
| Separation of Halides by Pyrohydrolysis | 24 to 27 |
| Fluoride by Ion-Selective Electrode | 28 to 30 |
| Chloride, Bromide, and Iodide by Amperometric Microtitrimetry | 31 to 33 |
| Trace Elements by Emission Spectroscopy | 34 to 46 |
1.3 The values stated in SI units are to be regarded as the standard.
1.4 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. (For specific precautionary statements, see Section 5.)
7.1 This test method covers the determination of boron in aluminum oxide-boron carbide composites. As an alternative, the procedure for total boron by titrimetry detailed in Test Methods C791 may be used.
14.1 This test method covers the separation of boron from aluminum and other impurities. The isotopic composition of the separated boron is measured using another test method found herein.
20.1 This test method covers the determination of the isotopic composition of boron in nuclear-grade aluminum oxide/boron carbide composite pellets containing natural to highly enriched boron.
24.1 This test method covers the separation of up to 100 ? g of halides per gram of sample. The separated halides are measured using other test methods found herein.
28.1 This test method can determine as low as 2- ? g of F/g sample in condensate containing all the halogens.
31.1 This test method covers the determination of halogens, except fluorine, as separated by pyrohydrolysis. The detection limit is 1.5 ? g Cl/g sample.
34.1 This spectrochemical test method provides for the determination of 14 impurity elements. The elements and concentration ranges are as follows:
| Elements | Concentration Range, ppm |
| Boron | 10 to 10 000 |
| Calcium | 10 to 10 000 |
| Chromium | 10 to 10 000 |
| Dysprosium | 30 to 10 000 |
| Europium | 10 to 10 000 |
| Gadolinium | 30 to 10 000 |
| Hafnium | 30 to 10 000 |
| Iron | 10 to 10 000 |
| Magnesium | 10 to 10 000 |
| Nickel | 10 to 10 000 |
| Samarium | 10 to 10 000 |
| Silicon | 10 to 10 000 |
| Sodium | 10 to 10 000 |
| Titanium | 10 to 10 000 |
34.2 The test method can also be extended to cover the determination of other elements of interest.
