摘要: The effect of chelation three alkaline earth metals (Ca, Sr, and Ba) by polyphosphates on the pH viscosity solution is examined correlated to phosphate glass properties. Also, impact polyphosphate average degree polymerization (Dp) as well type amount chelated divalent cation degradation rate chains studied. Subsequently, number cations required for chain agglomeration form a coacervate, resulting composition these coacervates, was investigated. A decrease in during routinely obtained, with sudden shift drop occurring around cation/phosphorus molar ratio 0.18. Longer or smaller ionic radius accelerated Dp reduction. coacervation depends different variables such concentration, Dp, cation. for...
