High purity and high whiteness quicklime is an industrial raw material with excellent performance. The CaO content in high-purity quicklime is usually ≥ 95%, and high-quality products can reach over 98%, far higher than ordinary quicklime. The total content of impurities (such as MgO, SiO ₂, Fe ₂ O3, Al ₂ O3, etc.) is ≤ 5%, and the content of heavy metals can be controlled at the ppm level, suitable for scenarios with strict purity requirements (such as food, medicine, electronic materials).
High whiteness quicklime has a pure white and uniform color, with a whiteness value of ≥ 90%. High end products can achieve a whiteness value of over 93%. Its appearance is delicate white powder or dense white lump, without yellowing, gray black and other impurities, and its visual quality is outstanding.
