Which point on a DTA endothermic peaks corresponds to the liquidus temperature of the salt mixture?
Hi,
The first peak will be Tg
second will be crystalline
third will be oxidation
fourth will be melting.
compare with your quotes with these. sure you will be getting an idea
Usually, the peak temperature of the last endothermic peak is the liquidus temperature
If you have identified the liquidus peak, the liquidus line point should be selected by the linear interpolation between the endothermic peak and the baseline. For convenience, in organic materials, the maximum value of the peak is selected as transition temperature, but in inorganic materials is taken at the beginning of the peak.
More information can be found in the book "DTA and Heat-flux DSC Measurements of Alloy Melting and Freezing".
