The thermal decomposition of natural iowaite of formula Mg6Fe2(Cl,(CO3)0.5)(OH)16.4H2O was studied by using a combination of thermogravimetry and evolved gas mass spectrometry. Thermal decomposition occurs over a number of mass loss steps at 60 degrees Celsius attributed to dehydration, 266 degrees Celsius and 308 degrees Celsius assigned to dehydroxylation of ferric ions, at 551 degrees Celsius attributed to decarbonation and dehydroxylation, and 644, 703 and 761 degrees Celsius attributed to further dehydroxylation. The mass spectrum of carbon dioxide exhibits a maximum at 523 degrees Celsius. The use of TG coupled to MS shows the complexity of the thermal decomposition of iowaite.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
