Summary Apparent and partial molal volumes of K‐kaolin and K 2 SO 4 , Mg‐kaolin and MgSO 4 , and Ca‐kaolin and CaCl 2 as a function of electrolyte and particle concentration were determined from density measurements at 30°C. The apparent (ø) and partial molal volumes ( V ) of the kaolin or the salts studied increase with concentration and are larger in salt‐clay mixtures. Kaolin saturated with electro‐strictive cations has lower volumes than that saturated with less strictive ones.
