Barium Sulfate Scale - Chemical Contaminant Removal

2019-12-5  For hard scales, such as barium sulfate, mechanical removal (scraping, sand blasting, chipping, jetting, controlled explosives) is the technique most often employed. Because scale is rarely deposited evenly on tubular goods, milling technology power requirements vary greatly.

Barium Sulfate - an overview ScienceDirect Topics

Barium sulfate is a soft crystalline solid. It is a rhombic crystal. The pure salt is white but the color of the mineral “barite” can vary between red, yellow, gray or green, depending on impurities. Its density is 4.50 g/cm 3 and its refractive index is 1.64. It melts around 1580 °C but decomposes above 1600 °C.

Recrystallization of 223Ra with barium sulfate SpringerLink

2014-5-4  In this work, the kinetics of barium sulfate recrystallization has been studied in acidic 0.01 mol dm−3 sodium sulfate solution using 223Ra and 133Ba tracers at very low total radium concentration, i.e. less than 10−13 mol dm−3. It was found that the system follows the homogeneous recrystallization model and that recrystallization rates, inferred by the decrease of 223Ra and 133Ba in the ...
