Ti 3 O 5, described as a Ti(IV)-Ti(III) species, is a purple semiconductor produced by reduction of TiO 2 with hydrogen at high temperatures, [41] and is used industrially when surfaces need to be vapor-coated with titanium dioxide: it evaporates as pure TiO, whereas TiO 2 evaporates as a mixture of oxides and deposits coatings with variable ...
Nickel titanium, also known as nitinol, is a metal alloy of nickel and titanium, where the two elements are present in roughly equal atomic percentages.Different alloys are named according to the weight percentage of nickel; e.g., nitinol 55 and nitinol 60.
Naturally occurring nickel (28 Ni) is composed of five stable isotopes; 58 Ni, 60 Ni, 61 Ni, 62 Ni and 64 Ni, with 58 Ni being the most abundant (68.077% natural abundance). [4] 26 radioisotopes have been characterised with the most stable being 59
Nb-Ti alloys have a maximal critical magnetic field of about 15 teslas and, thus, are suitable for fabricating supermagnets capable of generating magnetic fields of up to about 10 teslas. For stronger magnetic fields, higher performance superconductors, such as niobium–tin , are commonly used, but these are more difficult to fabricate and ...
The differences between tantalum and niobium were unequivocally demonstrated in 1864 by Christian Wilhelm Blomstrand [20] and Henri Étienne Sainte-Claire Deville, as well as Louis J. Troost, who determined the formulas of some of the compounds in 1865 [20] [21] and finally by Swiss chemist Jean Charles Galissard de Marignac [22] in 1866, who ...
Ni(III) can be stabilized by σ-donor ligands such as thiols and organophosphines. [44] Ni(III) occurs in nickel oxide hydroxide, which is used as the cathode in many rechargeable batteries, including nickel–cadmium, nickel–iron, nickel–hydrogen, and nickel–metal hydride, and used by certain manufacturers in Li-ion batteries.

For example, Ti (Z = 22) is in period 4 so that n = 4, the first 18 electrons have the same configuration of Ar at the end of period 3, and the overall configuration is [Ar]3d 2 4s 2. The period 6 and 7 transition metals also add core ( n − 2)f 14 electrons, which are omitted from the tables below.
