Thermal analysis and Hot-stage Raman spectroscopy of the basic copper arsenate mineral
Copper Arsenate Olivenite Cornwallite Cornubite Clinoclase thermal stage Raman spectroscopy Euchroite
<
2011/11/10
The thermal analysis of euchroite shows two mass loss steps in the temperature range 100–105 °C and 185–205 °C. These mass loss steps are attributed to dehydration and dehydroxylation of the mineral. ...
