Eutectic melting temperature

Fig. 1.29. Behavior of a su-crose-NaCI solution at different sucrose—NaCI concentrations and temperatures after quick freezing (200°C/min) during slow rewarming (Figure 8 from [1.25]). 1, Eutectic melting temperature of NaCI 2, crystallization temperature of NaCI 3, temperature at which the glass phase starts to soften 4, glass transition temperature...

MLiquid phase formed at the sodium disilicate-quartz interface above the eutectic melting temperature and worked its way outward. Perforation refers to when the outer sodium disilicate shells were no longer continuous. 

Ca, Sr, and Ba r and for Na and K F for Rb and Cs. In the presence of Na20 or NaOH, iodate ion undergoes disproportionation according to reaction (20). Calcium oxide or hydroxide caused some disproportionation to occur. Thus this behaviour of iodates in the presence of good oxide-ion donors is similar to that of chlorates. The reaction between IO3 and Br" ions in the LiBr-KBr eutectic melt (temperature range 420—483 °C) proceeds according to reaction (21), and lithium orthoperiodate separates out from solution. The initial rate of consumption of IO3 is first-order in [IO3]. 

Fig. 6.4-4 Phase diagram for the sucrose-water system, illustrating the locations of the glass, solidus, liquidus, and vaporous curves and the points and (eutectic melting temperature) corresponding to the intersections of the liquidus/glass and liquidus/ solidus curves, respectively [6.4.3]...

In contrast, the melting temperature of P(HN-co-CN) copolymer increases continuously with increasing CN content without showing a eutectic melting temperature. This indicates that P(HN-co-CN) copolymer shows isomorphic co-crystallization. " Crystallization modifiers like isophthalie aeid (IPA) and 1,4-cyclohexanedimethanol (CHDM) are often copolymerized into PET and PEN polyesters to form eopolyesters that have better processing properties. We will classify terephthalate and naphthalate polyesters as poly(arylate)s. 

Finally, on two points. Most maximally freeze-concentrated carbohydrates contain 80% w/w solids and 20% w/w unfrozen water [158] and that for ionic materials, crystalline freeze-dried materials are easily obtained when the is at temperatures above the eutectic melting temperature [159].
