Краткое описание

Highly dispersed CaO has been synthesized by heating an aqueous solution of calcium nitrate and D-glucose up to 800°C. Calcium oxide is formed with an average particle size of 0.4 μm. According to X-ray powder diffraction and DSC studies, after exposure to the air for 24 h at 25°C the sample consists of crystalline phases of hydroxide (17.7 wt %), carbonate (20.0 %), calcium oxide (up to 5.5 wt %), and up to 56.8 wt % of the sample consist of a non-crystalline X-ray amorphous CaO phase. The synthesized highly dispersed CaO has been stored in the air at 25°C for 7 days. According to X-ray powder diffraction and DSC methods, the obtained sample consists of crystalline phases of calcium hydroxide (12.8 wt %) and calcium carbonate (83.4 wt %). The calculations error does not exceed 10%.
