Abstract
Boron nitride (BN) based on chloride salt eutectic were tested for their specific heat capacities (SHCs) in this study. One way to measure the SHCs of nanomaterials is using a differential scanning calorimeter (DSC). Researchers measured the SHC of both the liquid and pure eutectic phases. The compound was originally a chloride salt eutectic with a sodium chloride to potassium chloride molar ratio of 65:35A surfactant that is well-suited for creating molten salt nanomaterials was found by combining three surfactants: gum Arabic (GA or surfactant C), sodium dodecyl benzene sulfonate (SDBS or surfactant A), and sodium dodecyl sulphate (SDS or surfactant B). The mass concentration of these three surfactants was set at 2% relative to the salt eutectic. In order to get the nanomaterials ready for dehydration, vials of water were heated on a hot griddle to evaporate the water. Using three different temperature settings, authors investigated how the nanomaterials’ SHC varied with the degree of nitride homogeneity in the substrate material: heats of 125, 145, and 165 °C. The quantity of agglomerated nitride should decrease as the evaporation temperature rises, as predicted (decreased evaporating time). Results showed that nanoparticles’ SHC increased by up to 22% while in a liquid form. Nanomaterials including SDS showed a greater time-dependent enhancement in SHC. Another possibility is that GA is the best solvent for dispersing BN in the salt solution. In addition, the present study contrasted the actual results with theoretical predictions of the SHC.
