Controlling raw material quality involves several steps:
1. Source Selection: Choose suppliers with a proven track record of providing high-quality raw materials. 2. Pre-treatment: Implement pre-treatment processes like calcination, washing, or drying to remove impurities. 3. Quality Control: Regularly test raw materials using analytical techniques to ensure they meet the required specifications. 4. Documentation: Maintain detailed records of raw material batches, including their source, composition, and any pre-treatment steps undertaken.
