AbstractThe incorporation of toxic heavy metals such as Pb, V, As, Zn, Cd, etc. into the apatite crystal structure is a potential solution to the problem of storage of these pollutants. For instance, apatite-type compounds are already applied to the treatment of lead-contaminated soils and waters (Chen et al. 1997; Zhang and Ryan 1999; Ioannidis and Zouboulis 2003) and are under consideration for the co-stabilization and recycling of incinerator ashes with industrial wastes (Taylor et al. 1998; Valsami-Jones 1998; Crannell et al. 2000; Dong et al. 2002; Dong and White 2004a,b; Kim et al. 2005). Therefore, an understanding of the stability relationships of apatites in terms of structure and chemical bonding is of interest.
