Study on the stability and microstructural properties of barium sulfate nanoparticles produced by nanomilling
CM Patel, M Chakraborty, ZVP Murthy - Advanced Powder Technology, 2014 - Elsevier
Barium sulfate nanoparticles were produced by nanomilling in stirred media mill using
sodium salt of polyacrylic acid (PAA-Na) as a dispersant. The particles sizes of the ground
product obtained in the grinding mill were determined by dynamic light scattering (DLS),
Brunauer–Emmet–Teller (BET) nitrogen gas adsorption method, and transmission electron
microscopy (TEM). The mean particle size calculated with various methods yielded different
values due to the different characterization techniques. The stability of BaSO 4 nanoparticles …
