Frequently Asked Questions
Kaolin is extensively used in ceramics for tableware and sanitary ware, in the paper industry as a filler and coating to improve brightness and smoothness, and in paints as a functional extender to control gloss and opacity.
High-purity Kaolin with low iron (Fe2O3) content prevents yellowing or spotting during firing, ensuring a crisp white color and higher structural strength in the finished ceramic piece.
Yes, we offer customized grinding and micronization services to ensure the Kaolin particles meet the specific technical requirements of your application, whether for fine coatings or bulk filler.
Raw Kaolin retains its plasticity and water content, ideal for molding. Calcined Kaolin is heat-treated to remove water, resulting in a non-plastic powder with higher brightness and chemical stability.
Absolutely. Our non-metallic mineral extraction processes adhere to strict environmental regulations to minimize land impact and optimize water recycling during the refining stage.
Every shipment is accompanied by a Certificate of Analysis (COA) detailing the chemical composition and a Material Safety Data Sheet (MSDS) for safety and regulatory compliance.
