Study on the development of thermal characteristics of B4C nanopowder and B4C/water using cryogenic conditions

Abstract

Deep cryogenic treatment (DCT), a technique that can be utilized on materials down to temperatures as low as −197 ℃, is used in this investigation to cool boron carbide nano-powder. Using the flash technique, researchers compare the thermal diffusivity of untreated and cryogenically treated B4C. Quantifying the thermal conduction of B4C nano-powders is another area of investigation. The results show that DCT significantly improves both the thermal diffusion and conduction of B4C nano-powder, by 34% as well as 47%, respectively. Additionally, the B4C/Water nanofluid's thermal conductivity is calculated. The results demonstrate that aqueous dispersion of both traditionally treated and cryogenically treated B4Cnanopowder improves its thermal conductivity. Because of their rapid Brownian motion, small particles are excellent thermal conductors.
