Barium sulfate Description
Barium sulfate. Its chemical name is BaSO 4 and its CAS registration is 7727-43-2. High-purity Barium Sulfate appears as a fine, white, crystalline, or amorphous powder that is tasteless, odorless and has a texture similar to white snow.
Barium sulfate is the main mineral form of barite and is an important source for its industrial products.
Its extremely low solubility is the most important and essential characteristic of Barium Sulfate in terms of its chemical properties. It is almost non-soluble in water and can be overlooked;
It is also insoluble in acids, bases and alcohols. This is why it has so many uses. Barium sulfate’s physical properties are dominated by its density of 4.3-4.5g/cm3, which makes it a heavy filler.
It also has high whiteness and high reflectivity, high coverage to light as well as low Mohs Hardness. These together determine its versatility in different industrial areas.
Barium sulfate is a powerful X-ray absorber due to its high atomic number. Its unique physical property makes Barium sulfate an indispensable contrast material for medical imaging.

The application of Barium sulfate
Key Features
Barium sulfate is a unique product with outstanding chemical and physical properties.
Its first and most important characteristic is its excellent chemical inertness. This makes it insoluble in almost all acids, bases and organic solvents. The product is able to withstand harsh conditions, including weather, corrosion, and maintain its properties.
Second, Barium Sulfate has a number of excellent physical characteristics: first, it is dense, making it a weight gain material ideal; second, the barium sulfate has incredibly high whiteness, and an excellent optical performance that can scatter light effectively, providing excellent coverage, and extinction while maintaining color purity.
Its lower Mohs hardness means it is less likely to wear down production equipment, such as screws and moulds, during processing. This makes it a soft filler.
The high atomic number in barium is responsible for its high absorption, which makes it a vital contrast material.
Barium sulfate: its main applications
Barium sulfate is used in a variety of key areas, including industrial manufacturing, human health, and many more.
Barium sulfate, also known as “industrial panacea”, is widely used in the chemical and manufacturing industry. It’s the “king” of functional fillers. It is used in high-end coatings because of its whiteness, chemical inertness and low wear resistance. This can improve the film’s thickness, hardness and weather resistance.
As a functional filler in the plastics and rubber industries, it can improve the strength, rigidity, dimensional stability and gloss of the products. It is used for products that need to gain weight due to its density.
High-purity Barium Sulfate, a component of high-end copperplate and color spray papers, is used to give the paper an extraordinary whiteness and smoothness. It also enhances the printing results.
Barium sulfate is a vital component in the energy and resource sector. It acts as a ballast stone. The high density of the barium sulfate is used in oil and gas drilling as a weighting material for drilling mud.
Addition of Barium sulfate to the drilling mud increases the static pressure, which can be used to balance high-pressure underground oil and gas reservoirs, prevent blowouts, and ensure the safety of drilling operations.
Barium sulfate, a raw industrial material that was once used to make sand, has undergone a remarkable transformation in the healthcare field. It is now a protector of life. High-purity, non-toxic and medical Barium Sulfate suspension is used as a gastrointestinal contrast agents by utilizing the fact that it is completely opaque to X rays.
It can be administered orally, and after enema it will cover the mucosa in the digestive tract. This will outline the contours and shape of the organs like the esophagus and stomach on X-rays. Doctors can use this “bright map”, to diagnose ulcers. This application is an example of materials science being used to benefit human health.

FAQ
It comes down to chemical refinement versus basic mechanical milling. Our precipitated barium sulfate—commonly traded as blanc fixe—is synthesized via a controlled chemical reaction. This process yields ultra-fine, submicron particles, a much tighter grain distribution, minimal abrasive impurities, and a flawless brightness profile that natural barite simply cannot match. Natural ground barite works well as a cheap weighting agent, but it lacks the chemical purity and consistent whiteness needed for high-end coatings and plastics.
We process and partition our blanc fixe into multiple commercial grades, spanning from 400 mesh up to ultra-fine 3000+ mesh configurations. Our baseline freight packaging consists of 25kg multi-wall paper valve bags fitted with an uncompromised internal PE moisture barrier. If your automated mixing lines require custom ton-bags or specific pallet wrapping, our logistics team can easily arrange that.
Because fine inorganic powders are highly susceptible to ambient humidity, always store the bags in a dry, sharply ventilated warehouse facility. Never stack the bags directly on concrete floors; use wooden or plastic pallets with clear floor clearance to ward off moisture uptake. Keep the material sheltered from rain during cross-docking and isolate it from flammable storage zones or strong reducing reagents to prevent cross-contamination.
Our baseline MOQ for standard industrial accounts sits at 1 metric ton (MT). However, we support technical teams during formulation trials by shipping out standalone 25kg sample bags. For full container loads or major spot volumes (20 MT and above), we handle palletization, customs clearance documentation, and dispatch within 5 to 7 business days.
