Implementation of ceramic slurries using oxyethylydenediphosphone acid as a component of an integrated defloculant

The composition of a complex deflocculant for a ceramic slip based on oxyethylidene diphosphonic acid (OEDPA) and components of a traditional thinner containing water glass and soda was selected. A comparative study of the influence of the proposed deflocculant and deflocculant Reotan SL by Lamberti on the rheological properties of the ceramic slip modified by them and the physical and mechanical properties of the cast samples was carried out. The deflocculant containing HEDPA allows achieving the minimum values ??of slip thixotropy, at which a high rate of casting is maintained for specimens characterized by lower shrinkage and increased strength characteristics.
