This can make it difficult to see the color of the indicator.
Barium sulfate added to the mixture binds to these particles, making them heavier.
Thus, it sinks to the bottom and leaves a clearer solution.

In colorimetry, barium sulfate is used as a near-perfect diffuser when measuring light sources.

Barium sulfate is usually obtained from barite, which is quite impure.
Barite is treated by thermo-chemical sulfate reduction (TSR), also known as carbothermal reduction, to obtain barium sulfide:
BaS04 + 4 C → BaS + 4 CO

In the laboratory, barium sulfate is produced by combining solutions of barium ions and sulfate salts.
Barium sulfate is the least toxic salt of barium due to its insolubility.
Wastes containing barium salts are sometimes treated with sodium sulfate to immobilize the barium.

Barium sulfate is one of the most insoluble salts of sulfate.
Its low solubility is used as a test for sulfate as well as Ba2+ ions in qualitative inorganic analyses.
Barium sulfate is reduced by carbon to barium sulfide.
Barium sulfate led to the discovery of the first synthetic phosphorus.
Sulfite, unlike sulfate, is soluble in water.

Soluble salts of barium are moderately toxic to humans.
However, Barium sulfate is not toxic due to its insolubility.
The most common route of unintentional barium poisoning is from consumption of soluble barium salts mislabeled as BaSO 4.

Barium sulfate is used in the manufacture of heat treatment salts.
Barium sulfate is used in the hardening of steel, in the manufacture of pigments, lubricants, PVC stabilizers.

Barium sulfate is an inorganic compound with the chemical formula BaSO4. Barium sulfate occurs in nature as the mineral barite. It is also used in various manufacturing applications and mixed into heavy concrete to serve as a radiation shield. This drug is used as a contrast agent in diagnostic x-ray procedures.

Therapeutic advantages of barium sulfate in diagnostic procedures include both its low water solubility and high level of clearance from the body. Barium sulfate is ingested by mouth or administered rectally and combined with granules of effervescent bicarbonate to enhance distension of the GI tract, allowing for enhanced gastrointestinal tract visualization,.

Barium sulfate is a sulfate of barium. It is used as a radiocontrast agent for X-ray imaging, in pigments, and to produce green light in pyrotechnics. Barium is a metallic alkaline earth metal with the symbol Ba, and atomic number 56. It never occurs in nature in its pure form due to its reactivity with air, but combines with other chemicals such as sulfur or carbon and oxygen to form barium compounds that may be found as minerals.

Barium sulfate is a type of lubricant additive widely used in the production of various lubricating oils and greases.
Barium sulfate is obtained from the reaction of acid and barium compounds.
This compound provides lubricants with excellent detergent, dispersant and anti-rust properties.
Barium sulfate is a very important ingredient in the industrial and marine sectors.
Since barium sulfate has a high melting point and is insoluble in water, it is used as a separating material in casting copper anode plates.

Anode plates are cast into copper molds.
Therefore, a fine suspension of barium sulfate powder in water is used as a coating on the mold surface to prevent direct contact of liquid copper with the solid copper mold.
Thus, when the molten copper solidifies in the form of an anode plate, it can be easily separated from the mold.
