在铁磷模拟HLW熔体和硼硅酸盐熔体DWPF内测量了六种耐火材料的动态腐蚀速度，测量在1000~1300°C之间进行.在铁磷熔体中，致密氧化铝和氧化铬耐火材料有最低的熔线腐蚀速度，二氧化硅、锆英石和AZS耐火材料的腐蚀速度比较高.同时，氧化铝和氧化铬耐火材料在铁磷熔体中的腐蚀速度小于它们在硼硅酸盐熔体DWPF中的腐蚀速度.对氧化铬耐火材料来说，其在三种含有模拟HLW废料的铁磷熔体中的熔线腐蚀速度<0.1mm/day.可以认为商品制造的致密氧化铝和氧化铬耐火材料是可以用来熔化很多铁磷HLW废料的，甚至可以熔化含有16wt%氧化钠的HLW废料.

The dynamic corrosion rate of six commercial refractories was measured in the iron phosphate melts containing simulated HLW and a borosilicate melt (DWPF) at temperatures from 1000 to 1300 C. A dense alumina and a chrome refractory had the lowest melt-line corrosion rate in the iron phosphate melts, whereas the corrosion rate for silica, zircon, and alumina-zirconia-silica(AZS) refractories was somewhat high. In general, the corrosion rate for the alumina and chrome refractory in the iron phosphate melts was no higher than their corrosion rate in the DWPF melt now used at the Savannah River Site. For the chrome refractory, the corrosion rate in three iron phosphate melts containing simulated HLW waste was under 0.1mm/day at the melt line. It is concluded that commercially manufactured, dense alumina or chrome refractories can be acceptable for melting many iron phosphate composition, even in wastes containing up to 16 weight percent soda
