Barium sulfate
Product Overview & Quality
- Product Name: Barium sulfate
- Brand: Kemaus (Product Code: KA-264)
- Grade: Analytical Reagent (AR Grade). Rigorously manufactured under premium Kemaus standards to ensure exceptionally low trace contamination of soluble barium salts, heavy metals, and arsenic. It provides outstanding chemical consistency for high-precision laboratory assays.
- Physical Properties: Odorless, heavy, fine white powder.
- Solubility: Practically insoluble in water, alcohol, and dilute acids. It exhibits exceptional chemical inertness.
- Key Use: Widely utilized in gravimetric analysis as a standard precipitate for the quantitative determination of sulfate ions. Used in analytical physics and optical research as a premium white reflectance standard for spectrophotometry calibration. Also applied as an inert chemical filler in polymer, coating, and materials science research.
Safety & Hazards
- Classification: Not classified as a hazardous substance according to GHS regulations due to its extreme insolubility, preventing human systemic absorption. Acts as a mild physical and mechanical dust irritant to tissues.
- Health Risks: Direct eye contact with fine dust may cause temporary mechanical irritation, watering, or short-term redness. Inhalation of large amounts of airborne dust may cause minor coughing, sneezing, or nasal discomfort.
- First Aid Measures: Flush eyes immediately with plenty of flowing water for at least 15 minutes. Wash affected skin with soap and water. Seek medical advice if irritation develops or persists.
Handling & Storage
- Storage: Store in the original, tightly sealed Kemaus container. Keep in a cool, dry, and well-ventilated space at stable room temperature (below 30 degrees Celsius). Extremely stable under normal environmental storage conditions.
- Precautions: Wear standard personal protective equipment (PPE), including laboratory gloves, safety glasses, and a particulate dust mask. Avoid generating large airborne dust clouds during handling.
