Web4 ore fa · This study investigates the effect of adding stearic acid (SA) on the thermal conductivity of polyamide 6 (PA6)/boron nitride (BN) composites. The composites were prepared by melt blending, and the mass ratio of PA6 to BN was fixed at 50:50. The results show that when the SA content is less than 5 phr, some SA is distributed at the interface … Web20 ott 2016 · The intersection of the calculated hBN melting curve with hBN cBN equilibrium line defines the hBN–cBN–liquid triple point at 3480 K and 5.9 GPa. Wentorf’s experimental data on hBN melting are in reasonable agreement with the calculated hBN melting. The experimental point at 6.7 GPa obviously corresponds not to hBN but to …
WebIn general, melting is a phase change of a substance from the solid to the liquid phase. The melting point of a substance is the temperature at which this phase change occurs. The melting point also defines a condition in which the solid and liquid can exist in equilibrium.
