“…Barium sulfate has scientific advantages like increasing thermal stability, crystalization rate, efficiency of resistance and improving the thermoluminesance characteristics of the compounds when its surface area is increased as its size reduce to submicron or nanometer scale . Nano BaSO 4 production can be done by breaking down processes such as grinding or by synthesis (formation) methods like reaction and precipitation .…”

“…Firstly, blending of micro-sized BaSO 4 particles physically into PU matrix did not influence mechanical properties negatively, as reported when particles of larger size were mixed in higher proportions. 9 With increasing BaSO 4 content, ultimate tensile stress of the composites remained in the same range of values, and elongation at break is larger than 650%. A slight increase in Young's modulus is measured in the composites, attributed to an increase in rigidity of matrix.…”

“…and Cui et al . demonstrated full shape recovery using BaSO 4 at 40% loading by weight, indicating that high concentrations of additives would not drastically alter the volume recovery . Additionally, BaSO 4 has been directly injected in the bloodstream due to errors during gastrointestinal imaging without long‐term complications, and leaches from doped catheters used in vascular applications …”

“…[12][13][14][15][16] In medical procedures, BaSO 4 is used for imaging contrast procedures, and to enhance opacity in dental adhesives and vascular devices, even at low concentrations (1.0%) when impregnated in solid polymers. 2,[17][18][19][20][21][22][23][24][25] Romero-Ibarra et al and Cui et al [26][27][28] demonstrated full shape recovery using BaSO 4 at 40% loading by weight, indicating that high concentrations of additives would not drastically alter the volume recovery. 26,27 Additionally, BaSO 4 has been directly injected in the bloodstream due to errors during gastrointestinal imaging without long-term complications, and leaches from doped catheters used in vascular applications.…”
