WhatsappManufacturing process of Strontium Carbonate
Step 1: Raw Material Selection
- High-purity strontium ore (Celestine) and carbon dioxide are selected.
- Raw materials undergo strict quality checks for purity.
Step 2: Chemical Reaction & Processing
- Strontium sulfate (Celestine) reacts with carbon dioxide in the presence of carbon to form Strontium Carbonate.
- The solution is filtered and refined to remove impurities.
Step 3: Precipitation & Drying
- The compound is crystallized, dried, and ground into a fine powder or granules.
Step 4: Quality Control & Testing
- The product is tested for assay, solubility, moisture content, and pH as per standards specification.
Step 5: Packaging & Storage
- Packed in HDPE bags or fiber drums to prevent contamination.
- Stored in a cool, dry place to maintain stability.
