WebIt means that if the p o 2 in the reaction system is controlled close to be less than equilibrium partial pressure, the thermal decomposition of hematite will accelerate at above 1500 K. It can also be calculated that the boiling temperature of the thermal decomposition of hematite in an open system is 1783 K, at which temperature hematite could … http://fr.scienceaq.com/Chemistry/100114001.html
WebDiluted acetic acid or formic acid may also be used in place of HCl acid. Different carbonate minerals in a rock specimen, immersed in an appropriate HCl solution for an appropriate period of time, will show different reactions. Minerals that show a weak reaction should be treated with warm HCl acid for about 30 seconds to 1 minute. http://reynolds.asu.edu/glg103_online/worksheet_pdfs/3B_AppE_min_id.pdf
