Product Overview & Quality

Product Name: Zinc powder (Zinc dust)
Brand: Kemaus (Product Code: KA-2312)
Grade: Analytical Reagent (AR Grade) with a premium zinc elemental purity of 96 percent or higher. Particle size and metallic consistency are strictly regulated under Kemaus premium quality controls, ensuring exceptionally low trace levels of interfering heavy metals (such as lead, cadmium, and iron) for flawless analytical baselines.
Physical Properties: Odorless, heavy, fine dark grey to silver-grey metallic powder.
Critical Chemical Nature: Highly reactive metal powder. In contact with water, moisture, acids, or strong alkalis, it undergoes an exothermic reaction and liberates highly flammable hydrogen gas.
Key Use: Heavily utilized as a powerful reducing agent in organic synthesis and metal precipitation assays. Frequently used in analytical protocols to reduce target ions prior to volumetric titrations, such as in nitrate determination tests. Also widely applied in electrochemical research, battery development, and materials science anti-corrosion coating studies.

Safety & Hazards (Critical & Flammable)

Classification: In contact with water, emits flammable gases. Flammable solid (in powder form). Very toxic to aquatic life with long-lasting effects.
Health Risks: Direct eye contact with metal dust causes temporary mechanical irritation and redness. Inhalation of concentrated airborne particles irritates the respiratory tract and may induce “metal fume fever,” characterized by flu-like symptoms, chills, coughing, and chest tightness.
Environmental Hazards: Highly hazardous to aquatic environments. Dispose of strictly in accordance with dangerous chemical waste regulations. Never wash down the drain.
First Aid Measures: Flush eyes immediately with plenty of flowing water for at least 15 minutes. Brush off loose powder from the skin, then wash thoroughly with soap and water. If inhaled, move the victim to fresh air immediately.

Handling & Storage

Storage: Severe Fire Hazard. Must be kept strictly dry and stored in its original, tightly sealed Kemaus container inside a dedicated cool, dry, and well-ventilated chemical storage zone at stable room temperature (below 30 degrees Celsius). Keep completely away from water, ambient moisture, strong acids, strong bases, strong oxidizing agents, open flames, and potential spark sources.
Precautions: Wear standard personal protective equipment (PPE), including laboratory chemical gloves, protective safety glasses, and a fine particulate dust respirator. Avoid generating dust clouds and prevent electrostatic discharge build-up during handling.
