Manufacturing process of Zinc oxide
Step 1: Raw Material Selection
- High-purity Zinc Ore or Zinc Metal is selected.
- Raw materials undergo strict quality checks for purity.
Step 2: Oxidation & Purification
- Zinc is oxidized at high temperatures to form Zinc Oxide (ZnO).
- The material is purified to remove impurities.
Step 3: Milling & Sieving
- The ZnO powder is milled and sieved to achieve the desired fine particle size.
Step 4: Quality Control & Testing
- The final product is tested for assay, particle size, pH, moisture content, and purity as per IP/BP/USP standards.
Step 5: Packaging & Storage
- Packed in HDPE bags or fiber drums to prevent contamination.
- Stored in a cool, dry place for maintaining stability.
