Rheological properties of ITO slurries prepared from nano-powders for gelcasting process

Preparation of aqueous ceramics slurry with high solid volume and low viscosity is premise and key step of gelcasting, and dispersant play important role in slurry preparation. In this paper, triammonium citrate (TAC) was used as dispersant of PMN-PZT piezoelectric ceramics slurry, the effects of TAC on slurry stability and rheological properties and dispersion mechanism of TAC were investigated by sedimentation test, viscosity, scanning electron microscopy (SEM) and FTIR analysis. The SEM results indicated that TAC could reduce the agglomeration of powder particles and make ceramic particles well-dispersed. FTIR indicated that strong chemical absorption occurred between TAC and PMN-PZT powder, and slurry stability and rheological properties of PMN-PZT slurry were improved through electrostatic interaction of TAC. The effects of TAC on sedimentation volume and viscosity have similar tendency. When TAC content was 7.5vol% and pH of slurry was about10, PMN-PZT slurry suitable for gel-casting could be acquired.

Main Substrate

Abstract A new monomer for application in the gelcasting process has been designed and synthesized, following the green chemistry trend to use non toxic and renewable compounds. Xylitol was the main substrate for the synthesis that included 3 stages. The final product, named 1-O-acryloylxylitol, was tested regarding its effectiveness as the processing agent for fabrication of alumina elements by gelcasting method. Rheological properties of the ceramic slurries were studied as well as the properties of shaped elements before and after sintering. The results are compared to those obtained by applying commercial monomer 2-hydroxyethyl acrylate.

The Relationship

Objectively and reliably determined indicators of rheological properties of the dough were identified using the alveograph device to create a system of classifications of wheat and flour from it for the intended purpose in the future. The analysis of the relationship of standardized quality indicators, as well as newly developed indicators for identifying them, differentiating the quality of wheat flour for the intended purpose, i.e. for finished products. To do this, we use mathematical statistics methods.
