The slurry then had a pH value of 3.8 and was allowed to cool and settle for 24 hours and a clear supernate (165 l) was removed; this supernate had a pH of 3.8 and contained 0.85 kg of rare earth oxides free from ceria. A creamy, limpid conditioned" slurry (471 1) free from lumpy material (unlike the original untreated slurry) was left in the tank.

Since the cure-width behavior is also different depending on dispersant characteristics, these factors should be considered when manufacturing a complex structure. The cure-width of the Slurry 180 was nearly twice of that of the Slurry 111.
