Abstract：

Molten　salt　is　an　extremely　promising　medium　for　heat　transfer　and　storage　in　Concentrating　Solar　Power　system.　Density　is　one　of　the　most　important　factors　directly　determining　capability　of　heat　transfer　and　storage.　An　experimental　system　was　improved　to　measure　density　of　high　temperature　molten　salt　with　Archimedes　method.　By　measuring　densities　of　LiNO3　and　Solar　Ssalt,　reliability　of　experimental　system　and　method　was　validated.　On　this　basis,　six　samples　from　KBr,　LiBr,　NaBr　and　CaBr2　were　made　up　according　to　different　mass　ratios.　Densities　of　samples　were　measured　with　the　experimental　system　at　380-580　and　fitted　as　functions　of　temperature.　The　results　indicate　that　CaBr2　is　key　factor　determining　density　values　of　quaternary　bromide　salts,　and　density　values　diminish　linearly　with　increasing　temperature　in　accord　with　density　change　of　most　known　molten　liquids.　©　2017,　Editorial　Board　of　Acta　Energiae　Solaris　Sinica.　All　right　reserved.
