However, the trend of better exothermic reaction
did not continue after the optimum loading of 5% AM.
From the results obtained, the following may be concluded: In-situ composites Al/Ti[B.sub.2] were produced with an exothermic reaction
in the Al-[K.sub.2]Ti[F.sub.6]-KB[F.sub.4] system, at 750-950 [degrees]C.
Although substantial amounts of aluminum were also recovered by a poor flux practice, aluminum is wasted when an excessive exothermic reaction
In the DSC test, a TA Instruments DSC 2010 (the calorimetric precision of DSC is [plus or minus] 0.1%) was used to obtain the exothermic reaction
curves of the SMC (sheet molding compound) paste samples.
Finally, the reaction rate would be indicative of an exothermic reaction
, and could be related to potentially reducing cure time since time and temperature are key elements when evaluating reactivity.
The bottle and foam feel warm because this is an exothermic reaction
in which energy is given off in the form of heat.
12CaO*7[Al.sub.2][O.sub.3] and 3CaO*[Al.sub.2][O.sub.3] produced a rapid exothermic reaction
against water to form xCaO-y[Al.sub.2][O.sub.3]-z[H.sub.2]O [22-26].
Considering the overall operating cost, the regeneration process has to be operated at high temperature with diluted oxygen to avoid the exothermic reaction
and further causes a deactivation of metal oxides.
Quadratic heat profile is assumed to be generated internally by the exothermic reaction
. An exothermic reaction
is a chemical reaction that releases energy by light or heat and the typical application of this process occurs in chemical industry.
The parameters enthalpy of activation energy and free energy obtained negative results that indicated exothermic reaction
and spontaneous nature of the sorption of metal ions.
The purpose of the exothermic reaction
is twofold: it allows larger pockets of entrapped aluminum to coalesce and fall back into the molten bath, and it facilitates reactions between aluminum and fluorides.
