The electric field effect on the viscosity of thermoplastic ceramic slurry and deformation of the component parts upon elimination of organic binders

The results of the study of the influence of the electric field on the viscosity of thermoplastic ceramic slips VK95-1, VF52.42-1 and on the deformation of castings when the organic binder is removed are presented. It was found that when a constant electric field is applied, the viscosity of the thermoplastic slip decreases, with an increase in the field strength from 10 ³ to 10 ⁶ V / m, the viscosity decreases 3 times. The electric field contributes to the preservation of the shape of the ceramic casting (without deformation) during the removal of the organic binder from it and makes it possible to significantly (6 times) reduce the duration of this technological operation.
