Titanium is considered the most biocompatible metal due to its resistance to corrosion from bodily fluids, bio-inertness, capacity for osseointegration, and high fatigue limit. Titanium's ability to withstand the harsh bodily environment is a result of the protective oxide film that forms naturally in the presence of oxygen.
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 ...
Titanium forms a variety of sulfides, but only TiS 2 has attracted significant interest. It adopts a layered structure and was used as a cathode in the development of lithium batteries. Because Ti(IV) is a "hard cation", the sulfides of titanium are unstable and tend to hydrolyze to the oxide with release of hydrogen sulfide. [12]
[1] [2] Titanium dioxide (TiO 2) and zinc oxide (ZnO) minerals are often utilized in sunscreens as inorganic physical sun blockers owing to their absorption of light in the UV range. As TiO 2 is proven to be more effective for blocking UVB and ZnO in the UVA range, the mix of these particles guarantees a broad-band UV shield.
In dialysis, sorbents like ferric oxide hydroxide and activated carbon can be used to remove toxins and positively charged ions from dialysate, thus reducing the amount of water needed for a ...
Titanium and its alloys are used in airplanes, missiles, and rockets where strength, low weight, and resistance to high temperatures are important. [14] [15] [16] Since titanium does not react within the human body, it and its alloys are used in artificial joints, screws, and plates for fractures, and for other biological implants.
Nitinol biocompatibility is an important factor in biomedical applications.Nitinol (NiTi), which is formed by alloying nickel and titanium (~ 50% Ni), is a shape-memory alloy with superelastic properties more similar to that of bone, [clarification needed] when compared to stainless steel, another commonly used biomaterial.
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 ...
