Product Introduction

Ultra-Fine and High-Performance for Quality Improvement

We offer calcite dust. This product reflects our pursuit of "ultra-fineness" and "high performance." We use natural high-purity calcite as the raw material. It is processed through dry grinding or wet grinding combined with precision classification technology.

Our factory covers over 20 acres and is equipped with advanced production equipment and a professional quality control team. We do not just supply raw materials-we support the quality improvement of your products. Our calcite dust is a high-performance material.

Key Specifications and Superior Quality

We maintain strict quality control throughout the entire process, ensuring stable chemical composition and excellent physical properties. The table below presents our key specifications.

The calcium carbonate content ranges from 95.0% to 98.0%. The whiteness ranges from 80% to 96%. The fineness is adjustable from 200 mesh to 1250 mesh, with a median particle size (D50) of 5 μm to 15 μm. We also strictly control MnO content at ≤0.006%, as it affects whiteness stability. Our calcite dust is designed for demanding applications.
