Aluminium titanium oxide is widely used in optical, photocatalytic and tribological applications. It is also a component in paints, cements and windows. The high light-reflecting properties and limited toxicity of TiO2 enable it to reduce energy costs and reduce pollution.
Various applications of TiO2 include photocatalysis, barrier coatings, barrier films, window glazing, and corrosion resistance. In addition, the oxide has high thermal stability and is low in toxicity. Moreover, it has many important applications, such as in solar cells and in coatings for ceramics and glass.
The nanometre sized TiO2 particles exhibit a large surface area, which has a profound influence on the internal structure of the matrix. This increases the interaction with other particles, thus improving the overall material's hydrophilicity. A small amount of hydrated silicon dioxide is used in an aluminium/titanium oxide, with a mole ratio of 0.1 to 20%.
Aluminum is added to the coating, which facilitates washing the pigment. Simultaneous addition of aqueous solutions of alkalized sodium silicate and aluminum sulphate in stoichimetric proportions forms a coating on the pigment.
Aluminium/titanium oxide with a mole ratio of 1:1 showed better performance than those with other mole ratios. Similarly, 0.05% nano TiO2 showed improved corrosion resistance.
The corrosion resistance was evaluated in a marine environment. The morphologies were investigated using transmission electron microscopy. Cerium oxide was incorporated into the aluminum metal matrix and it exhibited excellent antibacterial properties. Nanometer sized CeO2 demonstrated electronic conductivity, while microcrystalline cerium oxide demonstrated ionic conductivity.
