Monazite prepared at 1200°C in air was observed to incorporate cerium as 3+ and not 4+ even when charge compensation mechanisms for Ce4+ inclusion were present. The consequences of this phenomenon for the use of monazite structure-type solid solutions for transuranic nuclide isolation in radioactive waste management are discussed. The use of cerium as a substitute for the actinides is also considered.
