The Effect of Nanometer Oxide Additive on the Heat-Conducting Property of Barium Hydroxide Octahydrate.

Nanometer silicon dioxide additive can improve the thermal performance of barium hydroxide octahydrate as the phase change thermal energy storage material. Through measuring the changes of phase change temperature, degree of supercooling, thermal conductivity, the different effects of nanometer silicon dioxide additives of different mass fraction on barium hydroxide octahydrate thermal performance are compared. It can be seen that the precipitation of barium hydroxide octahydrate with nanometer silicon dioxide additive of 0.5% mass fraction improves greatly. The thermal conductivity of barium hydroxide octahydrate with nanometer silicon dioxide additive of 0.5% mass fraction increases to a very slight degree.
