Quicklime and hydrated lime difference: quicklime and slaked lime have the points. The main ingredient is calcium oxide lime (CaO) power plant with calcium oxide, white solid refractory insoluble. The (CaCO3) limestone content in the ventilation of the lime kiln calcination to obtain more than 900 ℃. The water absorption, the plant can be used as calcium oxide desiccant offer, our people used to prevent debris resurgence. Calcium oxide, calcium oxide plant supply, plant sales is an inorganic compound with calcium oxide, and its chemical formula CaO, quicklime common name. Physical properties of the surface of white powder, impure by an off-white, pale yellow or gray when containing impurities, hygroscopic. Physical properties: white or gray lumps or granules. Dissolved in acid, glycerol and sucrose solution, almost insoluble in alcohol. The relative density of 3.32 ~ 3.35. Melting point 2572 ℃. Boiling point of 2850 ℃. Refractive index of 1.838.
