This　paper　presents　a　new　kind　of　KNO3-NaNO3-LiNO3-Ca(NO3)(2)center　dot　4H(2)O　with　certain　proportion,　which　is　potentially　suitable　for　high-temperature　thermal　energy　storage　in　concentrating　solar　power　technology.　Its　primary　thermophysical　properties　were　evaluated.　Thermal　physical　tests　were　conducted　for　the　samples　obtained　at　different　stages　during　the　tests　of　1,200-h　exposure　to　constant　high　temperature　and　thermal　shock　cycling　for　1000　times.　Results　show　that　a　comprehensive　grasp　of　the　time　evolution　of　its-thermophysical　properties　and　their　respective　changes　with　heating　time　and　thermal　cycles　were　achieved.　The　thermophysical　properties　of　the　molten　salt　show　good　repeatability　before　and　after　the　experiments,　and　most　variations　are　within　+/-　10%.　In　addition,　the　normal　temperature　X-ray　diffraction　diagram　of　the　candidate　was　measured　and　analyzed　after　1200　h　of　heating　and　1000　times　of　thermal　cycling.　Although　part　of　calcium　nitrates　has　been　dissolved　and　formed　a　new　solution,　this　phenomenon　does　not　affect　the　performance　of　the　candidates,　which　showed　high-temperature　tolerance　and　good　thermal　stability.　Therefore,　this　new　kind　of　molten　salt　thermal　storage　materials　is　a　promising　candidate　for　both　heat　transfer　and　energy　storage　in　large-scale　solar　thermal　power　plants.
