The stability and dispersion behavior of the passivated titania whiskers were studied. The results show that the photocatalytic activity of the passivated titania whiskers is only 10% of fresh titania whiskers, and the stability and dispersion behavior of the passivated titania whiskers are better than those of fresh titania whiskers. Even if calcined or washed by organic solvent and inorganic solvent in ultrasonic cleaner, the photocatalytic activity of the passivated titania whiskers cannot be changed. XRD, SEM and ICP techniques were used to characterize the passivated titania whiskers. The results suggest that the main reason of the inhibition is calcium carbonate deposition on the surface of titania whiskers. %K titania whiskers %K photocatalytic activity %K inhibition %K stability %K dispersion behavior
