Meanwhile the experimental evidence includes as different processes as catalytic reactions [3,4], oxidation [5-81, sublimation [9] and desorption [lo]. Outside the critical region, i.e. for (TI 2: 1 with Looking for Hedvall effect II? Find out information about Hedvall effect II. A discontinuous change in the activation energy of certain substances at the Curie temperature. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Explanation of Hedvall effect II Download PDF: Sorry, we are unable to provide the full text but you may find it at the following location(s): http://repository.ias.ac.in/50 (external link) In the context of polymorph mechanochemistry, the Boldyreva group has provided an interesting example of the Hedvall effect: [123] the appearance of different outcomes upon thermal or mechanical 2016-6-27 · The magnetocatalytic effect (or Hedvall effect) refers to an abrupt change in the rate of a chemical reaction on a magnetic surface at the Curie point, T C [1]. The expla-nation for this unexpected link between magnetism and chemistry has remained elusive since its discovery in 1934 [2]. Careful surface science experiments [3] on The Hedvall effect was used to investigate the reactivity of calcium silicate hydrates (C- S-H) with variable C/S ratios. The solid state reaction between silver nitrate and various 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.

Sintering is defined as the bonding of adjacent surfaces in a mass of powder or a compact by heating . In general there are three types of sintering process including Solid-Phase (Dry) … Magnetic order is destroyed in a ferromagnetic material warmed above its Curie temperature.

A clearly observable internal magneto-catalytic effect was found for the runs done on the ferromagnetic catalyst, nickel, which has an approximate Curie temperature of 360°C. In order to confirm this effect, runs were done over the temperature range of 300°C to 500°C on the non-ferromagnetic catalysts, copper and platinum.
