Resumen:
The aim of this work is to study the synthesis and characterization of TiCb
powder by the Pechini method, to be used to ceramic membranes for application
in the water treatment. For one better understanding of the boarded subject, the
work was divided in three stages. The first stage consisted of the synthesis and
characterization of powder of TiC^. In this stage it was verified that the Pechini
method was efficient in the obtaining of nanosized powder (15,4 nm), pure and
crystalline. The second stage was referring at the development of the ceramic
membranes of TiC«2. It was verified in this stage that change in the type of tubular
support (dry or humidified in water) and the variation of the time of slip (30 and 60
seconds) for the deposition of the layer of Ti02, did not present variation in the size
of grain and neither of the pores of the layer of deposited TiC>2. It was because the
deposited layer didn't be homogeneity distributed on the supports. In the last stage
were made tests in laboratory scale, aiming at to the application of the titanium
ceramic membranes in the water treatment. In this stage it was concluded that the
tested membranes had presented good selectivity, with turbidez values less than
the CONAMA'S legislation, however, with relatively low flow.
