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.
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, 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]
A common reduced titanium oxide is TiO, also known as titanium monoxide. It can be prepared from titanium dioxide and titanium metal at 1500 °C. [4] Ti 3 O 5, Ti 4 O 7, and Ti 5 O 9 are non-stoichiometric oxides. These compounds are typically formed at high temperatures in the presence of excess oxygen.
Titanic acid is a general name for a family of chemical compounds of the elements titanium, hydrogen, and oxygen, with the general formula [TiO x (OH) 4−2x] n. Various simple titanic acids have been claimed, mainly in the older literature. [1] No crystallographic and little spectroscopic support exists for these materials.
Treatment is dependent on the specific type of cancer, location of the cancer, age of the person, and whether the cancer is primary or a recurrence. For a small basal-cell cancer in a young person, the treatment with the best cure rate (Mohs surgery or CCPDMA) might be indicated. In the case of an elderly frail man with multiple complicating ...
Metallosis is the medical condition involving deposition and build-up of metal debris in the soft tissues of the body. [1]Metallosis has been known to occur when metallic components in medical implants, specifically joint replacements, abrade against one another. [1]
