Precipitated Barium Sulfate Properties
Chemical formula: BaSO4, Molecular Weight: 233.39, CAS: NO.7727-43-7, National Standard: GB/T2889-2017, Appearance: Colorless Oblique Crystal or White No Styling Powder, Relative Density 4.50 (15℃), Melting Point 1580 ℃. MOHS hardness:3.0, Index of refraction: 1.64, Solubility: 20 ℃: 0.00024g/100g water. It can absorb harmful rays.It almost insoluble in water, ethanol, organic solvents, acids and alkalies. But it can dissolved in boiling hot sulfuric acid. It Is the only non-toxic common barium salt. It can be Reduced to barium sulfide and carbon dioxide at 600℃ by carbon.
Modified Barium Sulfate Application
F-series can be widely applied in modified plastics, transparent functional masterbatch, color masterbatch, engineering plastics and other industries,can significantly improve the mechanical properties of products, surface gloss and reduce production costs.

Modified Barium Sulfate's advantage for plastic
* Small particle size, low scattering rate, and very high transparency.
* Super dispersibility, no pits and high brightness
* Good resistance to acid, alkali and temperature can reduce the product color change.
* Stable whiteness, maintain color masterbatch stability
* High purity , no harmful substances to ensure the plastic products safety and cleanliness
* Low oil absorption, increasing the filler volume to reduce basis material and the cost.
* Good affinity to various resins,and improve various mechanical properties of plastic products.
Traditional Production Process
(1)BaS+Na2SO4=BaSO4↓+Na2S
The cost of the process is the lowest, but it has sodium sulfide byproduct, the finished product whiteness, impurities are generally unstable.
(2)BaS+H2SO4=BaSO4↓+H2S↑
The cost of the process is low, but the process has toxic hydrogen sulfide byproducts, equipment and environmental requirements..
(3)BaCl2+Na2SO4=BaSO4↓+2NaCl
This process is generally a by-product of some factories in the simple processing, few factories use this process.
(4)Ba(OH)2 +H2SO4=BaSO4↓+H2O
The process is simple, the cost of raw materials is high, but it will get high product purity, with the uniform and controllable particle size.
Our Preparation Process:BaCO3+H2SO4 =BaSO4↓+H2O+CO2↑
Compare With Traditional Preparation Process,using sulfuric acid and barium carbonate as raw materials, the production process does not produce harmful toxic gas, no water soluble salt by-products. Compared with the traditional production process.Our factory production process is simple, environmental protection, sustainable development.
