Calcium-based Materials Series
2 Products

CaO
Furman calcium oxide is produced by calcining high-grade limestone under precisely controlled temperatures and is available in three grades: FM800 (CaO + MgO ≥ 80%), FM900 (CaO + MgO ≥ 90%), and FM900S (CaO + MgO ≥ 90%, fine-particle grade). These products align with the EN 459 standard and deliver consistent performance across diverse applications, including construction materials (lime products, cement, lime mortar), the metallurgical industry (slag formers, fluxes, desulfurization agents), environmental protection (flue gas desulfurization, acidic wastewater neutralization, sludge solidification), sugar and food processing (neutralizing acidity in sugar juice, precipitating impurities), lubricants and petrochemicals (calcium-based grease thickeners, lubricating oil detergents), fine chemicals (calcium salt precursors, bleaching powder production), and soil improvement (roadbed stabilization, drying of wet soil). The FM900S grade features additional controls on particle size distribution, free water content, penetration, and air content, making it suitable for specialized applications requiring superior workability and dispersibility. Specific specifications are subject to the batch test report and Technical Data Sheet (TDS).

Ca(OH)2
Hanwei Technology’s calcium hydroxide is produced via a controlled hydration process and features a Ca(OH)₂ content of ≥ 95%. It appears as a white powder at room temperature, has a density of approximately 2.24 g/cm³, and a saturated aqueous solution pH of 12.4 (at 25°C). Benchmarked against the EN 459 standard, the product is available in four grades—FM100, FM100A, FM300, and FM700—to meet specific fineness and whiteness requirements across various applications. Key industrial uses include desulfurization in petroleum refining, thickening for calcium-based greases, food acidity regulation (E526), the manufacture of cement and furnace linings, metallurgical fluxing, and processes in the sugar, leather, and glass industries. Please refer to the specific batch test report and Technical Data Sheet (TDS) for detailed specifications.
