摘要：

In　order　to　satisfy　the　requirement　of　high　temperature　in　the　CSP　(Concentrating　Solar　Power)　and　solar　chemistry　industry,　we　choose　the　mixture　of　Magnesium　Chloride,　Sodium　Chloride　and　Potassium　Chloride,　which　are　stable　and　extensively　applied　in　heat　transfer　and　heat　storage　system　of　CSP.　Thirty　six　kinds　of　mixed　salts　with　different　weight　ratios　of　the　three　chloride　salts　were　prepared.　Melting　point　and　specific　heat　of　these　36　kinds　of　salts　have　been　measured　with　DSC　(differential　scanning　calorimeter).　The　results　showed　that　the　melting　points　of　these　salts　are　in　the　range　400C.　and　465C.　The　weight　ratio　of　the　mixture,　which　can　be　used　as　the　high　temperature　heat　storage　materials　with　the　lowest　thermal　storage　cost,　is　2(MgCl2):7(NaCl):1(KCl).　The　equation　for　calculating　the　capacities　was　derived　as　well.
