Hedvall 2 showed that calcium oxide would react with silver nitrate at a temperature considerably 1974-04-01 · A comparison with the investigations cited above (7-4) in which the Hedvall effect II is established shows an interesting pe- culiarity in all cases: irrespective of the catalyst nature (metal or semiconducting) and of the different magnetic ordering (ferro- or antiferromagnetic), the tempera- ture dependence of the rate constant be- comes steeper with the transition into the paramagnetic state (i.e., an increase in the activation energy is observed). THE increased reactivity of a solid during and as a consequence of a crystalline transformation is commonly known as the Hedvall effect 1-3. In a wider sense this effect may include increased reactivity near a transition point. The increased reactivity of a solid near a crystal transformation is known as the Hedvall effect. Hedvall² showed that calcium oxide would react with silver nitrate at a temperature considerably lower than the ``characteristic reaction temperature''.

In O2 flow, σ of a Na2SO4 sample and a O2-pretreated Li2SO4 sample increased initialy (Fig.6). This can be interpreted, in terms of diffusion of O2 into the crystal as a carrier owing to Hedvall effect … Hedvall-Effekt, Festkörperreaktionen.
