Description

Phosphate-based ceramics such as monazites are considered as potential host matrix for immobilization of long-lived trivalent and tetravalent actinides. Monazites are chemically stable with respect to leaching processes and have high radiation stability. Knowledge on thermodynamic stability of Ca and Th substituted LaPO4 is an important parameter which will govern the long term storage of thorium and minor actinides in this matrix. Differential Scanning Calorimetry (DSC) has been used to measure the molar heat capacity of La1-xCax/2Thx/2PO4(s) (x = 0, 0.25, 0.40, 0.60, 0.75, 1) compositions. (author)
