The chemical equation for the formation of barium sulfate precipitate is: Ba²⁺ + SO₄²⁻ → BaSO₄. Barium ions (Ba²⁺) react with sulfate ions (SO₄²⁻) to produce insoluble barium sulfate (BaSO₄), which precipitates out of the solution.

Precipitation of barium sulphate is not only widely used as a model system but also of considerable industrial significance, particularly in relation to its tendency to form scale in off-shore oil wells. Barium sulphate is the most important barium compound and the mineral barite (also called heavy spar or beryte), BaS04, is by far the most ...

Precipitated barium sulphate is a common chemically synthetic filler applied to polymeric raw materials, which can enhance the physical and chemical properties of products and reduce costs. Precipitated barium sulphate is a standard product with finer particle size, higher whiteness and purity, and greater stability than natural barite powder.

The 3D barium sulfate precipitation takes place in a tubular T-mixer consisting of a 10 mm long mixing pipe with a diameter of 1 mm. Two oppositely placed inlets each with a diameter of 0.5 mm are located at the top of the mixing pipe. An overview of the geometry can be seen in Figure 1. In 3D, barium chloride and sulphuric

There are two common paths to producing saturated barium sulphate solutions. The first is to add known amounts of sodium sulphate and barium chloride solutions into the vessel to precipitate the excess and and produce a saturated solution (S I = 1), according to Eq. (1) (Rosseinsky, 1957).
