2.1 x 10-5The other simulated silicate-agglomerated calcine samples tested
this quarter were all highly loaded with simulated sludge whose composition
was reported previously [STEINDLER-1980]. These samples, prepared by a new
technique, are called ambient-temperature silicate/sludge waste forms.
Because of the high loading of insoluble material, our method of studying
the dissolution/disintegration rate was ineffectual. A short description of
that procedure is as follows: samples to be tested are placed in a wide-mesh
stainless steel basket suspended by a Teflon cord from the bottom hook of a
