Industrial Grade Precipitated Barium Sulfate Economical Option for Warehouse Sales¹

Product DescriptionProduct DescriptionDescriptions of Precipitated Barium SulphatePrecipitated Barium Sulfate BaSO4 is precipitated (synthetic) barium sulfate produced by advanced technology, quality control standard higher than the GB standard. It is resistant to acids and alkalis, is an inert product which is lightfast and weather-resistant, has extremely high purity, pure brightness and whiteness, superior and uniform fineness, good dispersion and compatibility, ultra-low oil absorption and extremely stable chemical property. It is applied in large quantities by well-known manufacturers in paints and coatings, inks, plastic, masterbatch, rubber and art paper etc. Production Process of Precipitated Barium SulfatePrecipitated barium sulfate is primarily produced through a chemical reaction:Prepare Raw Material Solution: Barite ore is mixed with coal powder and roasted at high temperature to produce BaS ("black ash"), which is then soaked in water to create a BaS solution.Synthesis Reaction: The purified BaS solution is mixed with a sodium sulfate solution, reacting to form a precipitate of barium sulfate.Reaction: BaS + Na2SO4 → BaSO4↓ + Na2SPost-Processing: The precipitate is washed, dried, and milled to obtain the final product.Application of Precipitated Barium SulfatePrecipitated barium sulfate serves as a high-performance functional filler across a wide range of applications, including interior and exterior architectural coatings, marine and protective coatings, powder coatings, solvent- and water-based industrial coatings, printing inks, plastics and rubber, decorative laminating base paper manufacturing, among others.When incorporated into polyolefin color masterbatches, precipitated barium sulfate can partially replace color pigments—such as red, yellow, green, and blue—in varying proportions. Studies show that it can replace up to 20% of pigments on average without compromising coloring power, reflectance, or transmittance in final film or molded products. In fact, in some cases, it even enhances color performance while reducing production costs.Similarly, when used to replace 20% of titanium dioxide (TiO2), precipitated barium sulfate significantly improves the covering power and whiteness of white masterbatches without altering other key properties. It also enhances the dispersion of TiO2, regardless of its crystal type. The result is a masterbatch product with superior opacity, brighter whiteness, and better overall performance. Moreover, the selection of coating surface gloss remains equally as critical as color in achieving desired aesthetic effects.1. Architectural Coatings (Interior & Exterior)2. Marine & Protective Coatings3. Powder CoatingsPrecipitated barium sulfate enhances film thickness, hardness, and abrasion resistance. It improves corrosion resistance, weather durability, and storage stability, while also regulating gloss and improving adhesion.It offers excellent corrosion and chemical resistance, increases film density and mechanical strength, and extends the service life of structures in harsh environments.It improves surface smoothness, reduces orange peel, enhances powder application efficiency, and ensures better edge coverage and color consistency.4. Solvent-based & Water-based Industrial Coatings5. Printing Inks6. Plastics & RubberIt provides good compatibility, improves chemical resistance, hardness, hiding power, and suspension stability, and enhances light fastness and anti-aging properties.It adjusts viscosity and flowability, improves fineness, gloss, abrasion resistance, and adhesion to substrates.It increases rigidity, hardness, dimensional stability, heat resistance, and improves surface smoothness and color stability.7. Decorative Laminating Base PaperIt enhances opacity, whiteness, paper weight, and density, improves resin impregnation, and strengthens the wear, heat, and mechanical resistance of the final laminate.Characteristics of Precipitated Barium SulfatePrecipitated barium sulfate is a synthetic inorganic compound with the following characteristics:I. Physical properties1. Appearance: It is a fine, white, odorless powder. 2. Density: It has a relatively high density, usually around 4.5 g/cm3, which is much heavier than many other common inorganic fillers. 3. Particle size: The particle size can be precisely controlled during the manufacturing process, with particle sizes typically ranging from sub - micron to several microns, allowing it to be used in different applications that require specific fineness.4. Refractive index: It has a relatively high refractive index (about 1.64), which gives it good opacity and gloss - enhancing properties in coatings and plastics.II. Chemical properties1. Chemical stability: It is highly stable chemically. It is insoluble in water, organic solvents, acids (except hot concentrated sulfuric acid), and alkalis, making it resistant to chemical corrosion and suitable for use in harsh chemical environments.2. Inertness: It is chemically inert, which means it does not react easily with other substances under normal conditions. This property makes it an ideal filler in many chemical products, as it will not interfere with the chemical reactions of the base materials.III. Performance in applications1. Reinforcement: In rubber and plastic industries, it can enhance the mechanical properties of the products, such as improving tensile strength, abrasion resistance, and tear resistance.2. Coating performance: In the coating industry, it can improve the coating's durability, weather resistance, and hiding power, and also enhance the smoothness and leveling of the coating surface.3. Electrical insulation: It has good electrical insulation properties, so it can be used in electrical and electronic products to improve their insulation performance. PackagingIn 25kg,50kg,1000kg,1250kg Bag And OEM Color Bag.
