The Hamaker constant of anatase aqueous suspensions

The linear relationship of the yield stress with the square zeta potential may be used to determine the Hamaker constants in suspensions. In this work we have obtained the Hamaker constant for the attractive forces between anatase particles in aqueous suspensions using this method and compared them with those obtained by contact angle measurement. The results show excellent agreement. The linear relationship of the yield stress with the squared ζ potential may be used to determine the Hamaker constant in suspensions.
