Originální abstrakt

The article introduces the differences in the properties of whiteware (porosity, strength, thermal expansion coefficient) when non-traditional binder has been used. Pure calcium aluminate cement and the mixture of kaolin and calcium aluminate cement compared with traditional plastic raw material for whiteware - kaolin - are used for the preparation of whiteware bodies with constant content of non-plastic raw materials – K-Na feldspar and quartz sand. The results are discussed in connection with the microstructure of the fired body of prepared whitewares (mineralogical composition). Calcium aluminate cement CAC in whitevare raw material mixtures is an interesting alternative to kaolin for higher strength of green and fired body. Using calcium aluminate cement reduces the sintering temperature of the fired body and significantly changes its mineralogical composition - anorthite is the main mineralogical phase instead of mullite which is typical for a standard porcelain bodies made from raw material mixtures based on kaolin. The coefficient of thermal expansion increases with increasing content of CAC in raw materials mixture.
