Toward an Improved Understanding of the Marine Barium ...

 · Marine barite (BaSO4) is a relatively ubiquitous, though minor, component of ocean sediments. Modern studies of the accumulation of barite in ocean sediments have demonstrated a robust correlation between barite accumulation rates and carbon export to the deep ocean. This correlation has been used to develop quantitative relationships between barite accumulation …


Interfragmentary surface area as an index of comminution ...

 · All fragments were collected post-impact. They were then suspended in a specially prepared resin (Wood Epox ®, Abatron, Inc., Kenosha, WI), to which barium sulfate had been added to mimic the approximate CT density of soft tissue (+10 to +60 Hounsfield Units (HU)).Helical CT scans of these preparations were collected, using the same standard …


Characterisation and modelling of barium titanate-silver ...

Barium titanate-silver particulate composites were prepared by attrition milling BaTiO3 and silver nitrate, followed by conventional processing. After manufacture, microstructural, mechanical and electrical characterisation was undertaken to examine the …

Devitrified Barium Titanate Dielectrics - ULRICH - 1966 ...

Pure barium titanate was made into a glass by flame-spraying and after sufficient comminution was processed into specimens and fired. During this firing the glass devitrified to tetragonal barium titanate and contained crystals of sizes from 0.5 to below 0.2μ. The small crystals exhibit Curie temperatures from 120° to above 185°C.

Effective and irreversible removal of radioactive barium ...

 · The simultaneous high-capacity and fast removal of radioactive barium ion (Ba 2+) from nuclear wastewater is necessary but still faces large challenge.In this study, a novel adsorbent containing sulfonic group, MOF-808-SO 3 H, was prepared based on the oxidation of –SH group. Characterizations confirm the successful introduction of –SO 3 H, good porosity …


Study on Radiation Shielding Properties of New Barium ...

 · This study aimed to investigate the effect of BaF2 on the radiation-shielding ability of lead telluride glass. A physical radioactive source was used to estimate the mass attenuation coefficient (μm) of the 60TeO2-20PbO-(20-x)ZnO-xBaF2 glass system (where x = 1,2,3,5,6,7,9 mol%). We tested the μm values at seven energies (0.059, 0.081, 0.122, 0.356, 0.662, 1.173, …
