Product Overview

Our heavy calcium powder, derived from high-purity mineral sources, is a premium-grade material engineered for demanding industrial applications. With a CAS number of 471-34-1 and sourced from China, this white powder offers exceptional purity levels between 90% and 95%, making it suitable for a wide range of uses including coatings, paints, rubber manufacturing, papermaking, and construction materials. The consistent particle shape and controlled particle size distribution ensure reliable performance in every batch, supporting both industrial-grade and cosmetics-grade requirements with equal precision.

Technical Specifications

The table below outlines the key technical specifications for our heavy calcium powder product. These parameters are verified through rigorous quality control procedures to ensure compliance with international industry standards. The material's high whiteness (typically exceeding 92% brightness), low moisture content (under 0.2%), and uniform particle morphology contribute to its excellent dispersibility and compatibility with various binder systems. Whether used as a functional filler or a performance enhancer, this powder delivers consistent results across diverse manufacturing processes.

Industry Applications and Benefits

Heavy calcium powder plays a critical role in numerous industrial sectors. In paper manufacturing, its brightening and loading capabilities improve paper surface smoothness, increase opacity, and enhance printability. The addition of dolomite powder variants further aids in acid neutralization during the pulping process, extending the service life of paper products while reducing equipment corrosion. For coatings and paints, this powder acts as an effective extender and pigment, improving hiding power, scrub resistance, and weatherability while lowering overall formulation costs. In rubber and plastics, it improves dimensional stability, tensile strength, and thermal conductivity without compromising flexibility. The high purity of calcite-based powder makes it suitable for pharmaceutical and food additive applications, where inertness and compatibility with biological systems are paramount. Additionally, in construction materials (e.g., adhesives, sealants, and putties), it enhances workability, adhesion, and water resistance.

Beyond these core uses, our heavy calcium powder is also gaining traction in ceramic glazes, water treatment (pH adjustment and hardness control), and agricultural soil amendments (as a calcium source for plant growth). The ultra-fine particle grades (down to 325 mesh) ensure rapid dispersion in liquid systems, minimizing settling and agglomeration. These characteristics make the powder an indispensable raw material for modern industrial processes, driving innovation and efficiency across sectors.

Packaging, Customization, and Logistics

Our standard packaging is 25 kg/bag, supplied in sturdy, moisture-proof woven bags suitable for long-distance transport and storage. For customers requiring bulk handling or specialized packaging, we offer customized options including 1-ton big bags, 50 kg paper-plastic composite bags, or vacuum-sealed bags for high-purity applications. The minimum order quantity (MOQ) is just 1 kg, making it convenient for sample testing, laboratory evaluations, and small-scale production runs. We maintain a dedicated logistics network that ensures timely delivery to domestic and international destinations, with full traceability and documentation (including MSDS, COA, and RoHS compliance reports) provided upon request.

For large-volume orders, we offer bulk shipping options (e.g., 20 ft container loads, up to 22 metric tons per container). Our quality assurance team conducts thorough inspections at every stage of production—from raw material selection to final packaging—to maintain consistent particle size distribution, chemical purity, and whiteness. We also provide free technical support to help formulators optimize their recipes and achieve the desired performance characteristics.
