Witryna1 lis 2024 · To analyse the role of magnesium, the TGA of pure Mg(NO 3) 2 ·6H 2 O was performed. The thermal degradation is presented in Fig. 2 and this result corroborates what can be found in the literature: Mg(NO 3) 2 decomposition starts at 290 °C and ends at about 440 °C (Mu and Perlmutter, 1982).Therefore, the decomposition of this … WitrynaThe thickness of the melt film depends on the temperature, impurities, material properties and geometry. A temperature gradient is accompanied by a thermomolecular pressure gradient that drives the interfacial liquid from high to low temperatures and hence the particle from low to high temperatures, in a process called thermal regelation.
