Rutile　TiO2　is　often　used　as　an　anti-corrosive　carrier　material　for　titanium　anodes.　Because　SiO2　has　higher　corrosion　resistance,　better　wear-resistance　and　lower　cost,　an　attempt　has　been　made　in　this　paper　to　prepare　a　TiO2-SiO2　binary　carrier　material　from　anatase　TiO2　and　quartz　SiO2　through　mechanical　alloying　(MA)　method.　In　this　paper,　a　binary　oxide　whose　molar　concentration　was　75%TiO2-SiO225%　was　obtained　by　30h　mechanical　alloying.　The　phase　structure　and　particle　morphology　of　the　prepared　material　were　examined　by　means　of　XRD,　DTA　and　TEM.　It　is　indicated　that　after　MA:　(1)　the　particle　sizes　of　anatase　TiO2　has　been　fined,　nanometer　crystals　have　appeared.　However,　the　reduce　effect　on　SiO2　crystal　size　has　not　been　so　obvious.　(2)　The　morphology　of　the　obtained　oxide　particles　has　been　typically　equiaxal.　(3)　The　phase　transformation　from　anatase　TiO2　to　rutile　TiO2　has　taken　place　and　its　starting　temperature　has　been　decreased　by　about　350°C,　compared　with　the　result　of　the　conventional　method.　(4)　A　kind　of　solid　solution　of　SiO2-TiO2　has　formed　in　the　obtained　oxides.　The　non-equilibrium　solid　solution　of　TiO2-SiO2　is　difficult　to　be　achieved　from　the　conventional　method.
