Description
Summary:The results of an investigation of the effect of an electric field on the viscosity of thermoplastic slips of the ceramic VK95-1 and VF52.42-1 and on the deformation of the castings occurring when the organic binder is removed are presented. It is determined that when a constant electric field is applied the viscosity of the thermoplastic slip decreases. When the field strength increases from 10 3 to 10 6  V/m the viscosity decreases by a factor of 3. An electric field helps to preserve the shape of the ceramic casting (with no deformation) during the removal of the organic binder from it and makes it possible to decrease substantially (by a factor of 6) the duration of this technological operation.
