Titanium dioxide has been found to be toxic to plants and small organisms such as worms, nematodes, and small arthropods. [22] The toxicity of TiO 2 nanoparticles on nematodes increases with smaller nanoparticle diameter specifically 7 nm nanoparticles relative to 45 nm nanoparticles, but growth and reproduction are still affected regardless of ...
Titanium dioxide, also known as titanium(IV) oxide or titania / t aɪ ˈ t eɪ n i ə /, is the inorganic compound derived from titanium with the chemical formula TiO 2. When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. [4] It is a white solid that is insoluble in water, although mineral forms can appear ...
[1] [3] Decomposition in water is not hazardous, and therefore titanium butoxide is often used as a liquid source of titanium dioxide, which allows deposition of TiO 2 coatings of various shapes and sizes down to the nanoscale. [4] [5] Titanium butoxide is often used to prepare titanium oxide materials and catalysts. [6] [7] [citation needed]

Titanium(II) oxide (Ti O) is an inorganic chemical compound of titanium and oxygen. It can be prepared from titanium dioxide and titanium metal at 1500 °C. [ 1 ] It is non-stoichiometric in a range TiO 0.7 to TiO 1.3 and this is caused by vacancies of either Ti or O in the defect rock salt structure. [ 1 ]
