Effect of B2O3 on Iron Phosphate Glass-Ceramic Wasteforms
摘要
Abstract
The effects of doping iron phosphate glass-ceramic wasteforms containing high level waste (HLW) with different B2O3 contents on their structures and properties were investigated. The chemical durability of glass-ceramic wasteforms was measured by dissolution rate (DR) method. The structure of the glass-ceramic wasteforms was analyzed by Fourier turning infrared (FTIR) and X-radiation diffraction (XRD). The results show that glass-ceramic wasteforms have the main crystalline phase of monazite. There are great effects of wasteforms on the chemical durability. The 28 d leaching rate of glass-ceramic watesforms is 7. 81×10-9 g/(cm2·min) when 10% (mole percent) Fe2O3 is replaced by B2O3 in watesforms. Samples exist a large number of [PO4]3-, a small amount of [P2O7]4- and no [PO3]-. Boron in wasteform samples is present as tetrahedral [BO4] units.关键词
