Combustion of levitated titanium particles in air

Combustion synthesis of titania nanoparticles in a premixed methane flame

“…In general, the size and shape of the nanoparticles are important for industrial applications, such as ease of milling and high opacity of the powder [12]. The photocatalytic efficiency of anatase titania has proven to be better than rutile titania, which is thus more favorable for filtering polluted air and wastewater [13]. Additionally, the ability to control characteristics of the functional nanoparticles or nanotubes through flame synthesis would improve the final product and save energy [14].…”

A comparative study of TiO2 nanoparticles synthesized in premixed and diffusion flames

“…The physical and chemical behavior of TiO 2 nanoparticles must be understood to design and control various processing parameters [1][2][3][4][5]. The majority of the research on the synthesis of TiO 2 photocatalysts is focused on conventional wet syntheses such as precipitation, impregnation, and sol-gel techniques.…”

Combustion synthesis and development of Ti–O–C aluminium composites

“…This could evidence transformation of ␣-Ti to ␤-Ti, that is present in the binary system at 882 • C. Then, although the pyrometer did not record the so high temperature, probably fusion of Ti particles proceeded, as well as transport of oxygen and its dissolution in the particles. In the researches of combustion Ti in air [9,10] it was found that the reaction kinetics depended on oxygen adsorption. Concentration of oxygen increased linearly to finally form Ti 2 O 3 .…”
