Where, i polluting compounds (CO2, HCL HF, SO2, etc.); j constituting elements (C, Cl, F, S, etc.) of the polluting compounds, yi emission (in mg of compound i per kg of ceramic produced); LOI (°o) loss on ignition at the sintering temperaturę 1020*C of each materiał; Mwi molecular weight of the polluting compounds; Amj atomie mass of the element; Crj concentration of element (j) in the raw materiał and Cfj concentration of element (j) in the fired product.
