Quicklime is produced by high-temperature calcination (above 900 °C) of high-quality limestone (high calcium purity), then adjusted to lump, granular, or powder form (through crushing and screening). Quicklime produced at our manufacturing sites is used across various fields, particularly by steel, paper/pulp, and civil engineering users. Additionally, quicklime produced in the Yamaguchi area is used as a raw material in the magnesia products we manufacture at the Magnesia Division, making it a core product in our lineup.
