摘要：

In　order　to　enhance　the　specific　heat　of　LMPS,　which　is　a　new　kind　quaternary　nitrate　mixed　salt　with　low　melting　point,　adding　SiO2　nanoparticles　into　it　to　synthetize　the　nano-LMPS　by　two　methods:　ultra-sonication　and　melting-　mixing　in　high　temperature.　The　effects　of　the　two　synthesis　protocols　on　the　nanoparticles　dispersion　in　nano-LMPS　have　been　studied.　Furthermore,　the　effects　of　nanoparticles　dispersion　on　enhancing　the　specific　heat　of　molten　salt　have　been　researched.　Results　showed　that　the　specific　heat　capacity　of　nano-LMPS　has　been　significantly　improved　by　adding　nanoparticles.　And　the　increasing　rate　of　specific　heat　capacity　is　positively　correlated　with　the　uniform　degree　of　nanoparticles　dispersion.　The　specific　heat　capacity　increasing　rate　of　nano-LMPS　prepared　by　ultra-　sonication　is　higher　than　the　nano-LMPS　prepared　by　the　method　of　melting-mixing.　©　2017,　Editorial　Board　of　Acta　Energiae　Solaris　Sinica.　All　right　reserved.
