H ẹ dvall-Effekt ein von dem schwedischen Physiker A. Hedvall (* 1888, † 1974) erkannter Effekt, wonach eine Verbindung im festen Zustand bei ihrer beginnenden thermischen Zersetzung eine besondere Bereitschaft zur chemischen Reaktion mit einem beigemischten Festkörper zeigt (chemische Reaktionen im festen Zustand).
This can be interpreted, in terms of diffusion of O2 into the crystal as a carrier owing to Hedvall effect with the phase transition reaction. In NH3 flow, σ of mono-component samples increased in the order of Li2SO4 In NH3 flow, σ of mono-component samples increased in the order of Li2SO4

Alla illustrationer av Per-Olof Hedvall, utom ICF-modellen i kapitel 4 som är gjord factors impact an individual's possibilities to act in concrete. 2009, s. THE increased reactivity of a solid during and as a consequence of a crystalline transformation is commonly known as the Hedvall effect1–3. In a wider sense this effect may include increased reactivity near a transition point. The typical data quoted in support of the Hedvall effect refer to reactions in the binary systems containing silver salts with BaO, SrO and CaO yielding the reciprocal

The Hedvall effect was used to investigate the reactivity of calcium silicate hydrates (C–S–H) with variable C/S ratios. Written on 11 October 2018 . Erik Hedvall. Written by Arkitekterna Krook & Tjäder on 14 December 2020 . Erik Marklinder. 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''. DOI: 10.1007/BF00549714 Corpus ID: 135757747.

2018-2-9 · the Hedvall effects, i. e. the afterations of the activity of nickef in the Curie interval. The diagrams obtained show with great certainty that the activation energy and the frequency factor of the p-n-H2-conversion are smaller above than below the Curie tempe-rature of nickel. This result is in line with the known behaviour of the adsorption
