Phosphate glasses have some properties superior to those of borosilicate glasses. Among these are lower melting temperature, higher solubility for molybdenum and better chemical durability for some alkali-low glasses. The high corrosion of metallic containers by the melt was overcome by using refractory-lined melters. The tendency for the phosphate glass to crystallize was suppressed by rapidly cooling small beads. The beads were then embedded in a lead matrix to yield a composite nuclear waste form (1).
