Description / Table of Contents:
Consecutive reactions of artinite (MgCO3 ·Mg(OH)2 · 3 H2O) into magnesite (MgCO3) through hydromagnesite (4MgCO3 Mg(OH)2 · 4 H2O) were studied directly by an X-ray diffraction method under hydrothermal conditions using a micro autoclave results were discussed from the point of kinetic analysis. Both reactions from artinite to hydromagnesite and from hydromagnesite to magnesite were of first order with apparent activation energies 21 kcal/mol, 12 kcal/mol respectively.
Notes:
Die Umwandlungen des Artinits (MgCO3 · Mg(OH)2 · 3 H2O) in den Hydromagnesit (4 MgC03 · Mg(OH)2 · 4 H2O) und weiter in den Magnesit (MgCO3) wurden röntgenographisch unmittelbar unter hydrothermalen Bedingungen in einem Mikro-Autoklaven untersucht und kinetisch analysiert. Beide Reaktionen sind von erster Ordnung; Aktivierungsenergien: etwa. 21 kcal/Mol bzw. 12 kcal/Mol.
