Originální abstrakt

Influence of typical ceramic deflocculant – sodium hexametaphosphate – on the rheological properties (viscosity) of calcium aluminate cement paste, porcelain raw materials mixture (casting slip), and fired porcelain body respectively, was determined. It was used two different typed of calcium aluminate cements (from two sources – producers - Istra, Almatis) with different content of Al2O3 (40 % and 70 %). Sodium hexametaphosphate decreases of water content needed to prepare slip casting with constant viscosity. Deflocculant increases the modulus of rupture MOR of dried green body and its bulk density. Sodium hexametaphosphate admixture is very suitable for the creation of porcelain body with low porosity after firing.
