摘要：
In this paper, the rheological behaviors of dispersions of two types of clays a kaolin and a smectitic clay - from Paraiba State, Northeastern Brazil, were investigated. Both clays are mainly employed by ceramics industries in the Southern States of Sao Paulo and Santa Catarina. Viscosity measurements of dispersions in water and three types of alcohols (methanol, ethanol, and propanol) were carried out in a concentric cylinder geometry viscometer. The concentration of the dispersions was 20 wt.% of clay in water-alcohol suspensions containing up to 75 wt.% of each one of the three alcohols. The results are compared and discussed.
