Rheological Investigations of Clay Suspensions for the Optimization of Deflocculation Process

The rheological properties of clay aqueous suspensions are investigated in order to optimize the deflocculating dosages. The effects of four deflocculants have been investigated on the slip casting performance. The laboratory study on the deflocculation of casting slips has yielded the parameters from which the most efficient and economically advantageous deflocculant or mixture of deflocculants can be proposed for each ceramic body.
