The impact of oxalate ions on barium sulfate crystallization [PDF]

open access: yes, 2018
In this manuscript we investigate the impact of oxalate ions on the crystallization of barium sulfate. The organic anion, oxalate, was found to inhibit both nucleation and growth according to atomic force microscopy measurements and dynamic light ...

The impact of sulfite ions on barium sulfate crystallization [PDF]

open access: yes, 2019
In this manuscript we investigate an inorganic, anionic promoter of barium sulfate crystallization. Sulfite ions are found to promote barium sulfate crystallization at low concentrations. Turbidimetric experiments show homogenous nucleation promotion and
