*3.3. TEM Analysis*

By using TEM micrograms at various magnifications to better examine the morphology of the BaSO4 nanoparticles, Figure 4 was created. Due to their strong magnetic interaction and large surface area due to their nanoscale size, the produced BaSO4 nanoparticles were found to be crystalline and include agglomerated irregular particles with an average size of 30–60 nm (Figure 4).
