Глинозем, преимущественно используемый для производства алюминия. Определение потери массы при 1000 и 1200 град. С
Название (англ.):
Aluminium oxide primarily used for the production of aluminium; Determination of loss of mass at 1 000 degrees C and 1 200 degrees C
Описание (англ.):
The temperatures are arbitrarily selected and specified because there is no specific calcination temperature. There is no criterion for the state of calcination. Therefore, ignition of two test portions taken from the same sample and previously dried in a muffle furnace for 2 h. Calculation by difference in mass. Replaces ISO Recommendation R 806/1968.
