Barium Sulfate CAS 7727-43-7 | Look Chemical
Barium sulfate is among the most extensively made use of inorganic substances in industry and medicine today. When overseas users look for “what is barium sulfate,” they typically want concise info concerning the basic interpretation, chemical formula, safety, and viability for particular applications of BaSO
As a global chemical supplier, Look Chemical supplies secure, high-purity barium sulfate (CAS 7727-43-7), extensively made use of in finishings, plastics, piercing fluids, battery materials, and clinical imaging representatives.
Barium sulfate, with the chemical formula BaSO₄, is a white crystalline powder widely recognized for its extremely high stability, high density, and excellent opacity. Common questions about solubility, such as “Does barium sulfate dissolve in water?” or “Can barium sulfate dissolve?”, frequently arise.
The scientific answer is: Barium sulfate is insoluble in water. It is almost completely insoluble in water and most solvents, therefore it is safe to ingest in certain medical applications.
What Is in Barium Sulfate?
Barium sulfate is a widely used chemical material, but what exactly is it composed of? This is a question many overseas customers are interested in. The answer is actually quite simple:
The core components of barium sulfate are primarily barium ions (Ba²⁺) and sulfate ions (SO₄²⁻). The combination of these two ions forms a structurally stable ionic crystal, which is key to barium sulfate’s excellent performance. Normally, barium sulfate contains no additives, maintaining its pure chemical structure. However, in certain special applications, such as in the plastics industry, coated barium sulfate may undergo further surface treatments, such as stearate treatment, to optimize its performance.
This simple yet efficient composition determines the wide application of barium sulfate in multiple fields, especially in the chemical, plastics, and medical industries. Whether you are concerned with its purity or special modification schemes, it can meet different performance requirements.
Related Questions:
A: Barium sulfate is a white, odorless, water-insoluble inorganic compound commonly used in industrial filler applications and also widely used in medical imaging.
A: No. Barium sulfate is extremely poorly soluble in water; therefore, in medicine, it is considered a safe imaging aid.
A: Some people may experience mild bowel movements after taking medical-grade barium sulfate for examinations. This is because the suspension can irritate the digestive tract, but it does not have a laxative effect.
A: A small number of people may experience temporary diarrhea, bloating, or mild abdominal discomfort after ingesting medical-grade barium sulfate. However, these symptoms usually subside on their own within a few hours.
A: Barium sulfate (BaSO₄) does not chemically react with substances in the body. It primarily acts as an inert substance, adhering to the walls of the digestive tract, thus clearly displaying the gastrointestinal structure on X-rays or CT scans.
A: If any discomfort occurs, it usually lasts only a few hours to 24 hours, depending on the individual’s digestive system condition.
A: If vomiting occurs, the medical team may rearrange or adjust procedures. It is important to note that industrial-grade barium sulfate is never for consumption.
A: If you have purchasing needs, you can choose the Look Chemical website. This supplier has a stable global shipping volume and provides documents such as MSDS, COA, and REACH, and supports efficient and fast international logistics services.
A: Separation can be achieved by utilizing the difference in their solubility. Since BaSO₄ is insoluble in water, while NaCl is completely soluble, the mixture can be dissolved in water and then filtered for separation.
A: Barium sulfate is an ionic compound, composed of Ba²⁺ cations and SO₄²⁻ anions.
Applications of Barium Sulfate
Barium sulfate has a wide range of applications, playing a crucial role in several industrial sectors:
1. Coatings and Paints: As a high-whiteness filler, barium sulfate possesses excellent hiding power and weather resistance.
2. Plastics and Masterbatches: Adding barium sulfate to plastics improves the material’s rigidity, dimensional stability, and UV resistance.
3. Rubber Products: It enhances the strength of rubber while reducing chalking.
4. Oil Drilling (API Grade): Due to its high density, barium sulfate is often used as a weighting agent in drilling mud.
5. Pharmaceuticals and Medical Imaging (Radiography Grade): Medical-grade barium sulfate is used in X-ray or CT scans to significantly improve image clarity.
6. Batteries, Ceramics, and Powder Coatings: It provides these materials with excellent insulation properties, high brightness, and high-temperature stability.
Auxiliary substances added during the polymerization process, such as initiators, catalysts, emulsifiers, dispersants, molecular weight regulators and terminators. Its functions include initiating polymerization reactions, improving polymerization speed, adjusting system viscosity, controlling branching reactions and molecular weight, and improving polymer properties…
