The titania coating on phosphate surface was made by the painting method in air and at room temperature. The coatings were dried at 25°c and sintered at 15(TC, 25(FC, 350”C, 45ƠJC, 550°C for 30 minutes. X-ray diffraction, scanning electron microscopy and the cutting method (TCVN 2097-1993) were used to characterize the coatings. The results showed that the coating annealed at 350TC had the high photoactivity in the photodegradation of methylene blue.
