Hydrous sodium polysilicates are available as powders with bulk densities from 80 to 650 g/L and compacted granules with bulk densities in the range 750-950 g/L. Particle sizes are between 80 and 700 pm [2,11,65]. Made from sodium silicate solutions, they may contain 16-22 wt% moisture [1,5,7,11]. Water uptake is generally limited by their tendency toward caking at higher moisture levels. They are x-ray amorphous and have no defined stoichiometry [19,65]. The composition is...
