Precipitated Barium Sulfate

Precipitated Barium Sulfate for High-Whiteness Coating Formulations

Precipitated barium sulfate is a refined, super-fine white BaSO₄ powder for industrial applications that require high whiteness, fine particle control, stable chemical properties, and reliable dispersion. It is suitable for coating manufacturers, printing ink producers, plastic compounders, rubber processors, paper producers, ceramic plants, enamel manufacturers, and selected barium salt applications.

This grade has a BaSO₄ content of at least 98.00%, whiteness of at least 95.00%, and a specific gravity of 4.50 at 15°C. Its controlled particle-size distribution and low 45 μm sieve residue make it suitable for industrial formulations where filler quality can affect surface finish, coverage, appearance, processing stability, and consistency between production batches.

Foshan Xintu Chemical Co., Ltd. supplies precipitated barium sulfate in standard 25 kg plastic woven bags for bulk industrial procurement. Alternative 500 kg and 1,000 kg packing options can be discussed according to order volume, warehouse handling conditions, and shipping requirements.

Why Use This Grade in Industrial Formulations

High Whiteness for Appearance-Sensitive Products

Coating, ink, plastic, and paper producers often need mineral fillers that support a clean, uniform appearance in finished products. This precipitated barium sulfate has a whiteness value of at least 95.00%, making it relevant for white, light-colored, and color-sensitive formulations.

• Whiteness of at least 95.00%
• Suitable for formulations where color consistency is important
• Helps support a clean visual appearance in coated or molded products
• Relevant to white, light-color, and pigment-containing formulations

Fine Powder for More Consistent Dispersion

Particle distribution can influence mixing behavior, coating smoothness, ink quality, and the final appearance of plastic or rubber compounds. This product is supplied as a super-fine powder with controlled particle-size data for industrial evaluation.

• At least 80.00% of particles are below 10 μm
• At least 60.00% of particles are below 5 μm
• At least 25.00% of particles are below 2 μm
• 45 μm test sieve residue of no more than 0.10%

Stable Chemical Properties for Manufacturing Use

Precipitated barium sulfate is insoluble in water, organic solvents, and common acids under normal industrial handling conditions. This chemical stability supports its use as a functional mineral filler in formulations where the raw material must remain stable during storage, compounding, mixing, and downstream processing.

• Molecular formula: BaSO₄
• CAS No.: 7727-43-7
• EINECS No.: 231-784-4
• pH value of 100 g/L water suspension: 6.5–8.0
• Water-soluble substance: no more than 0.20%

Technical Considerations Before Procurement

Match Whiteness and Fineness to Your Formula

Buyers should confirm the required whiteness, particle-size range, and sieve residue based on the finished product and process conditions. For coatings and inks, these indicators can affect smoothness, coverage, gloss, visual uniformity, and dispersion. For plastic and rubber compounds, they should be assessed together with resin type, pigment package, processing temperature, and loading level.

Review Oil Absorption for Resin and Binder Balance

The oil absorption value of this grade is 15–20 g/100 g. This figure should be reviewed together with the resin, binder, solvent system, additives, viscosity target, and filler loading used in the buyer’s formulation. Internal laboratory or production-line trials are recommended before confirming high-volume procurement.

Confirm Storage and Delivery Arrangements

The product should be stored in a dry and clean warehouse, protected from moisture, contamination, and bag damage. Before placing an order, buyers should confirm the required packing format, target delivery location, container arrangement, and unloading capacity at the destination.

Typical Procurement Case

Mineral Filler Evaluation for an Industrial Coating Producer

An industrial coating producer needed a high-whiteness mineral filler for regular water-based and solvent-based coating production. The purchasing and technical teams required clear information on BaSO₄ content, whiteness, particle-size distribution, oil absorption, packing format, and expected delivery time before proceeding with supplier evaluation.

Buyer Requirement: The customer needed a precipitated barium sulfate grade suitable for internal formulation testing, with BaSO₄ content of at least 98.00%, whiteness of at least 95.00%, low sieve residue, and standard industrial packing suitable for warehouse storage.

Solution: Foshan Xintu Chemical Co., Ltd. provided the available technical data for the grade, including BaSO₄ content, whiteness, particle-size distribution, oil absorption, pH value, and 25 kg bag specifications. The buyer could compare these indicators with internal raw-material specifications and arrange sample or bulk-procurement discussions according to the intended coating system.

Result: The purchasing team received the practical data needed to assess formula compatibility, calculate storage requirements, and prepare a bulk inquiry based on expected consumption, packaging preference, and destination logistics.
