| titleOfInvention | METHOD FOR PRODUCING CALCIUMSILICATSULFATCHLORIDE |
| abstract | The invention relates to the preparation of calcium silicate sulphate chloride of the formula Ca2-SiO4CaSO4CaCl2, which has hydraulic activity. The pure compound can be doped with oxides of suitable elements (eg, rare earths) and then has luminescence properties. Another property of this compound is the irreversible migration of chloride ions from the excitation region upon electron irradiation, thereby changing the area of the electron beam hit by the chemical composition. The preparation of the novel compound is carried out by preparing a mixture consisting of (a) a calcium sulfate such as anhydrite or gypsum, (b) at least one reactive calcium compound such as calcium oxide, calcium carbonate or calcium oxalate, (c) calcium chloride or a CaCl 2 -containing component and (d) SiO 2 or an SiO 2 -rich compound and heated at temperatures in the range of about 550 to 890C for a period of about 10 minutes to about 20 hours. In addition to pure compounds, starting materials may also be waste products such as belite sludge, gypsum from flue gas desulphurisation, flue gas itself, salted coal, calcium chloride lye, peat leaching residue, FeSi dust, etc. |
