Sodium polyphosphate, crystal,+200 mesh, 96%
Based on 1 Customer Validation
Sodium polyphosphate, crystal,+200 mesh, 96% is an inorganic polyphosphate that also serves as a stabilizer, dispersant, chelating agent, and coacervate-forming agent. Sodium polyphosphate provides electrostatic stabilization for mineral and material suspensions, but its dispersing efficacy decreases under acidic pH, high temperature, high calcium concentration, or a combination of these conditions. Sodium polyphosphate can chelate alkaline earth metals, reduce solution pH, and alter the rate of pH decline at a divalent cation/phosphorus molar ratio of 0.18. Sodium polyphosphate forms coacervates with smaller divalent cations and precipitates with larger divalent cations, where the functional requirements of cations depend on polyphosphate concentration, average degree of polymerization, and cation type.

Biological Activity
Sodium polyphosphate exhibits the best dispersion effect on 50 wt.% suspensions of aluminate- and zirconia-coated aluminum-doped rutile titanium dioxide pigments in the fresh state; its dispersion performance decreases after pretreatment at acidic pH (3.5) and 90 °C for 24 h; and the dispersion performance further declines with longer pretreatment time, lower pH, or higher temperature[1].
