        Addition of about 10% K2O to Fe3O4 lowers the activity of this catalyst, though small amounts of both K2O and MgO increase the activity.  These effects are due to the alkalinity of the added compounds, which causes more rapid desorption of the NH3.  Catalysts containing K2O are easily decomposed by air.  Addition of K2O and Al2O3 increases the stability of the catalyst toward heat.
