Real-world notes on Strontium Chloride from the factory floor to QA

If you buy chemicals for a living, you know the difference between a tidy spec-sheet promise and what actually lands in the drum. Over the past year, demand for Strontium Chloride has ticked up—mostly from pyrotechnics and specialty glass folks—and, to be honest, the market has been picky about moisture and trace Ba/SO4. That’s where China’s FIZA team (Origin: Zhongyuan Building, No.368 Youyi North Street, Shijiazhuang, China) has been getting buzz for its anhydrous grade: “Best price, premium quality,” as their sales note puts it, but the interesting part is their willingness to customize.

What it is and why people buy it (now)

Chemically, Strontium Chloride (SrCl2, CAS anhydrous: 10476-85-4) is a highly soluble, white crystalline salt that readily forms a hexahydrate. It shows up in red-color pyrotechnics, as a precursor for other Sr salts, in certain specialty glasses/ceramics, and—surprisingly to newcomers—in legacy desensitizing toothpaste lines that still qualify SrCl2·6H2O. A lot of customers say consistency beats headline purity: they’d rather have 99.2% that stays dry and low in Ba/Fe than a fragile “99.9%” that hydrates in transit.

Typical product specification (Anhydrous)

How it’s made (short process flow)

Materials: strontium carbonate (or hydroxide), hydrochloric acid, deionized water. Methods: controlled dissolution and CO2 removal → filtration/clarification → evaporation and crystallization (often hexahydrate first) → dehydration under dry HCl/N2 sweep or with suitable dehydrating conditions → screening and nitrogen packing. QA: ICP-OES for Sr/trace metals; AgNO3 titration for chloride; Karl Fischer for moisture; laser diffraction for PSD. Labs usually run to ISO 17025; plant under ISO 9001; GHS/CLP labeling compliant.

Applications and advantages

• Pyrotechnics: stable red flame source using Strontium Chloride blends; consistent granulation reduces dusting.
• Glass/Ceramics: precursor feed for strontium-containing formulations where chloride route is preferred.
• Dentifrice (legacy): SrCl2·6H2O for desensitizing lines; documentation matters more than ever.
• Lab/industrial synthesis: clean Sr source; fast dissolution is a time-saver.

Vendor snapshot (what buyers compare)

Case notes from the field

A mid-size EU fireworks plant swapped to FIZA’s Strontium Chloride after moisture drift caused clumping in a competitor’s lots. Their QA logged 99.5% SrCl2 (ICP) and 0.18% H2O (KF) on arrival; dust levels dropped ~15% during mixing, and red tone consistency improved batch-to-batch. Another buyer in specialty glass moved to a low-Ba grade; their melt analyses showed Ba below 300 ppm without process tweaks. Not dramatic, but in real production, that’s meaningful.

Testing, safety, and storage

Common tests: ICP-OES for metals, Mohr/Volhard chloride titration, Karl Fischer moisture, sieve/laser PSD. Safety: classify per GHS/CLP; avoid dust inhalation and eye contact; use dry storage with liners and desiccant. Real talk: Strontium Chloride loves water—keep drums sealed; once opened, use promptly or re-pack with nitrogen if possible.

Customization checklist

• Moisture cap (≤0.2% target) and anti-caking aids (if allowed)
• Granule size windows for reduced dust
• Low-Ba/low-Fe grades for optical uses
• Documentation: COA lot-specific, SDS, regulatory letters (REACH/RoHS)
• Packing: 25 kg drums with inner PE + foil; palletization for humid lanes
