Safety and Handling
Strontium carbonate is non-combustible and stable under normal conditions. It may cause mild irritation to eyes, skin, or respiratory tract upon prolonged exposure. Chronic inhalation risks include potential bone density effects due to strontium’s similarity to calcium. Always use in well-ventilated areas with PPE, including gloves, goggles, and dust masks. Store in cool, dry conditions away from acids. For detailed guidelines, refer to SDS standards.
Frequently Asked Questions (FAQs)
What is strontium carbonate used for in glass manufacturing?
Strontium carbonate is added to glass formulations to improve refractive index and reduce radiation, making it ideal for TV screens and optical lenses. It replaces barium compounds for lighter, clearer results.
Is strontium carbonate soluble in water?
No, it is highly insoluble, dissolving at just 0.01 g/100 mL at 20°C. This property ensures stability in aqueous environments.
What are the health risks of handling strontium carbonate?
Short-term exposure may irritate skin or eyes. Long-term inhalation could affect bone health. Use protective gear and follow OSHA ventilation guidelines.
Can it be used in fireworks?
Yes, it produces a striking red color due to strontium ions emitting light at 606-660 nm. It’s a preferred ingredient for safe, vivid displays.
How does it benefit ceramic production?
It enhances sinterability and magnetic properties in ferrites, leading to stronger, more efficient components for motors and transformers.
What purity levels do you offer for industrial use?
Our standard grade is 99.5% pure, with options up to 99.9% for electronics. Bulk orders include full certification.
