“…In a previous work we proposed a new deflocculent based on oxyethylidenediphosphonic acid (OEDPA, empirical formula C 2 H 8 O 7 P 2 ) in combination with soda and liquid glass [5,6]. It was found that such a ternary system gives a clay suspension with lower viscosity and thixotropy in a wide range of concentrations.…”

The composition of a complex deflocculent for ceramic slip based on oxyethylidenediphosphonic acid (OEDPA) and components of a conventional thinner containing liquid glass and soda is found by trial and error. A comparative study is performed of the effect of the proposed deflocculent and the deflocculent Reotan SL (Lamberti Co.) on the rheological properties of the ceramic slip modified by them and the physical-mechanical properties of the castings. The deflocculent containing OEDPA makes it possible to minimize the slip thixotropy for which the casting rate of the samples, characterized by higher shrinkage and characteristics, remains high.

“…Also, the authors proved that the quantity of MPBMA is higher than 0.20%, the ceramic suspension exhibits Newtonian behavior and excellent dispersion. Kotova et al [15] studied the effect of a complex additive based on soda, liquid glass and oxyethylidene diphosphonic acid on the rheological and mechanical properties of cast ceramic articles. They observed that the viscosity and thixotropy of the suspension decreased to minimal values, as well as an increase in the strength and density of the dry and fired clay samples with a decrease in shrinkage and porosity.…”

The slips intended for the manufacture of ceramics must have rheological properties well-defined in order to bring together the qualities required for the casting step (good fluidity for feeding the molds easily settles while generating a regular settling of the dough and for the dehydration phase of the dough in the mold a setting time relatively short is required to have a sufficient refinement which allows demolding both easy and fast). Many additives have added in slip of ceramic in order to improve their rheological and mechanical properties. In this study, we investigated the impact of xanthan gum on rheological and mechanical properties of ceramic slip. The modified Cross model is used to fit the stationary flow curves of ceramic slip at different concentration of xanthan added. The addition of xanthan gum in a concentration range between 0 and 0.4 wt % in slip of ceramic induces the increase in the yield stress, zero shear rate viscosity and the infinite shear rate viscosity of the slip of ceramic. Generally speaking, the presence of xanthan gum modifies the rheological and mechanical properties of the slip. On the other hand, the study shows that an increase in flexural strength with the increase of the amount of xanthan gum in the ceramic slip. All the experimental results indicate an increasing tendency of the interactions between the particles of the raw materials with the highest concentration of xanthan gum.
