Criteria for Evaluating Quality CaCO3 Powder Suppliers

To select a suitable CaCO3 powder supplier among the hundreds of companies in the market, businesses typically rely on the following core technical and capability criteria:

• High purity content: Quality CaCO3 powder must have a calcium carbonate content of 98% or higher. Impurities such as silica, iron oxide, and aluminum oxide must be kept at very low levels to avoid affecting the physicochemical properties and quality of the final product.
• Outstanding whiteness and brightness: For industries such as premium paint, white paper, or plastic masterbatch production, the whiteness and brightness indices are typically required to reach 95% to 98%, and can even go up to 99%.
• Precise fineness and uniform particle size distribution: The supplier must have an ultra-fine grinding system using modern technology. Particle size must meet the committed micron specifications, from D50 to D97, to ensure good dispersibility and minimize clumping during mixing.
• Production and delivery capacity: The supplier needs a large factory capacity, a stable source of raw materials from mines, and a professional logistics system. This factor helps ensure on-time delivery, even for large-scale orders ranging from hundreds to thousands of tons per month.
