Mechanism for decomposition of aurichalcite—A controlled rate thermal analysis study
Frost, Ray L., Locke, Ashley J., Martens, Wayde N., Hales, Matthew C., Vagvolgyi, Veronika , & Kristof, Janos (2008) Mechanism for decomposition of aurichalcite—A controlled rate thermal analysis study. Thermochimica Acta, 468(1-2), pp. 81-86.
Controlled rate thermal analysis (CRTA) of a series of synthetic aurichalcite (Zn,Cu2+)5(CO3)2(OH)6 with the ratio of Cu/Zn varying from 0.1 to 0.5 proves that the dehydroxylation and carbonate loss occur as non-isothermal and isothermal decompositions. The temperature of the thermal decomposition increases as the Cu/Zn ratio increases. Thermal decomposition of aurichalcite provides a method for preparing mixed oxide catalysts at the molecular level as opposed to the particle level. CRTA technology enables separation of the processes of dehydration, dehydroxylation and decarbonation. X-ray diffraction of the products of the thermal decomposition proved to be a mixture of the oxides ZnO and Cu2O.

Citation countsare sourced monthly fromand 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.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
