        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.
