Barium kommt wegen seiner hohen Reaktivität in der Natur nicht elementar, sondern nur in Verbindungen vor. Mit einem Anteil von etwa 0,039 % ist Barium das 14.häufigste Element der Erdkruste.. Barium wird vor allem in den Mineralen Baryt (Schwerspat = kristallisiertes Bariumsulfat) und Witherit (Bariumcarbonat) gefunden, wobei Baryt die häufigsten Vorkommen hat.

Barium sulfate is almost always used in such coatings where the gloss of the top coat is important. Chemical inertness makes it of great value in coatings that require chemical resistance when used under high acid conditions. Add barium sulfate solution to soluble barium salt such as barium chloride, and the resulting precipitate is washed, filtered, dried, crushed, and sieved to become a ...

Barium sulfate is one of the most difficult types of scale to inhibit in oil and gasproduction systems because of its physical hardness and its chemical and thermal stability [74]. Barium sulfate is most commonly inhibited with either phosphonate or polymeric scale inhibitors deployed at substoichiometric concentrations. The effect resulting from the use of combinations of two or more scale ...

However, pure barium sulfate dries to a powder and easily rubs off surfaces. We sought to increase the durability of barium sulfate by mixing it with untinted white latex paint. Reflectance and durability of different ratios of this BaSO 4 and paint mixtures were measured from 430 to 950 nm with an ApogeeStellarNet spectroradiometer.

· 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. When motors cannot supply the power needed for the bit to cut the scale, the motor stalls and the milling process .
