This product was prepared by synthesizing a suspension of titania powder using tetraethyl orthosilicate (TEOS) at two concentrations (w/v): 1% and 4%, in the presence of the n-octylamine surfactant. After the application of titania-silica composite, the rocks were submitted to contact angle test, spectrophotometry, sorptivity, thermal shock resistance and UV radiation resistance tests.
