Low Temperature Ceramic Waste Form: Characterization of Monazite Cement Composites
Central to the concept of geologic waste isolation is the design of a stable radioactive waste form. This paper describes research on an alternative low-temperature ceramic waste form. The concept is to utilize modified calcium silicate, aluminate and other cements as matrix solidification utilizing a hydration bonding or other low temperature bonding mechanism. Previous workers have shown that conventional cements are suitable for solidifying a variety of wastes (1). Advantages of cement-based solidification include relative ease of processing (2) and potentially low cost; indeed, intermediate level wastes have been incorporated in cementitious grouts at ORNL for a number of years (3).
