The effect of fluoride ions on the viscosity, yield point, pH, and conductivity of hydrogen‐clay slips and a calcium‐clay slip is shown. These data indicate that fluoride ions deflocculate hydrogen‐clay slips by the same mechanism as hydroxyl ions because these ions are isoelectric and approximately the same size. The data tend to confirm the electrocratic theory of deflocculation. The fluoride ion was not effective for deflocculating the calcium‐clay slip.
