Abstract: | To investigate the often-made statement that low-temperature ashing leaves the structure and composition of the mineral residue unaltered, 25 salts and 20 minerals were studied by X-ray diffractometry and infrared spectrophotometry. It is concluded that many substances remain unaltered, but some do not, so the statement is misleading. |
