Product Features
High purity: Precipitated barium sulfate has a high purity and very little impurity content, which enables it to ensure the stability and reliability of product quality in industrial and laboratory applications.
For example, in the pharmaceutical industry, high-purity barium sulfate is a high-quality raw material for the production of pharmaceutical excipients and can be used for gastrointestinal radiography, etc.
Chemical stability: It has good chemical stability and is not easy to react chemically with other substances. In industrial production, barium sulfate can remain stable in various complex chemical environments, such as in the coating, plastic and other industries, which can enhance the chemical stability and corrosion resistance of the product.
Insolubility: Precipitated barium sulfate is almost insoluble in water and most organic solvents, which makes it play an important role in many applications. For example, in paints and inks, barium sulfate can be used as a filler to improve the hiding power and gloss of the product without affecting the performance of the product.
High specific gravity: It has a high specific gravity, which makes it advantageous in some applications where the weight or density of the product needs to be increased.
For example, in the rubber industry, adding barium sulfate can increase the weight and hardness of rubber products and improve their wear resistance and aging resistance.
Industrial Applications
Coating Industry: In coatings, precipitated barium sulfate acts as a filler and body pigment, which can improve the hiding power, gloss and weather resistance of coatings. It can keep coatings stable under different environmental conditions, prevent aging and fading of coatings, and extend the service life of coatings.
Plastic Industry: Used in plastic production, it can improve the hardness, wear resistance and chemical corrosion resistance of plastic products. Barium sulfate can also improve the processing properties of plastic products, making them easier to shape and process.
For example, adding barium sulfate to plastic products can enhance the mechanical properties and appearance quality of products.
Rubber Industry: As a filler for rubber products, precipitated barium sulfate can increase the hardness and strength of rubber, and improve the wear resistance and aging resistance of rubber products. In rubber products such as tires and rubber tubes, the addition of barium sulfate can improve the performance of products and extend their service life.
Papermaking Industry: In the papermaking industry, barium sulfate can be used as a filler and whitening agent for paper. It can improve the whiteness, opacity and gloss of paper, and improve the physical properties of paper, such as strength and flexibility.
Laboratory Applications
Chemical Analysis: Precipitated barium sulfate is often used in chemical analysis, such as gravimetric analysis and colorimetric analysis. It can be used as a reference substance to calibrate analytical instruments and verify the accuracy of analytical methods.
Medical Imaging: In medical laboratories, high-purity precipitated barium sulfate is the main raw material for the preparation of medical barium sulfate preparations, which is used for digestive tract imaging examinations to help doctors observe the morphology and function of the digestive tract.
Catalyst Carrier: In some chemical reactions, barium sulfate can be used as a catalyst carrier to provide a stable support structure for the catalyst and improve the activity and selectivity of the catalyst.
Precautions
Storage Conditions: It should be stored in a dry, well-ventilated environment to avoid moisture and contamination. Moist barium sulfate may affect its performance and reduce its purity.
Safety of Use: Although barium sulfate itself is less toxic, during production and use, protective measures should be taken to avoid inhalation of barium sulfate dust to prevent potential harm to the human body.
Quality Control: In industrial and laboratory applications, the quality of barium sulfate should be strictly controlled to ensure that its purity and performance meet relevant standards and requirements. Regular quality inspections of barium sulfate should be carried out to ensure the stability of product quality.
