Ultra-Fine and High-Whiteness Grade for Demanding Requirements
We supply calcium hydroxide powder for dental applications, developed with a focus on ultra-fine particle size and high whiteness. High-quality limestone is selected as the raw material and processed through high-temperature calcination, precise hydration, fine grinding, and purification. Our factory operates six automated production lines with an annual capacity of 300,000 tons. Our R&D team includes nine senior engineers specializing in ultra-fine powder grinding technology. We are more than a supplier-we are a trusted expert in calcium hydroxide materials. This is our premium-grade product line.
Key Specifications and Superior Physical Properties
Strict quality control is applied throughout the entire production process to ensure stable chemical composition and excellent physical performance. The following table summarizes our high standards. High-quality limestone ensures consistency from the source. Testing is carried out in accordance with HG/T 4120-2024, ensuring the Ca(OH)₂ content meets a minimum of 95%.
Through advanced ultra-fine grinding technology, the product achieves a fineness of 325 mesh, with a 45μm sieve pass rate of ≥98%. Whiteness reaches ≥92%, which is excellent for calcium hydroxide materials used in high-end applications.
