Titanium hydride normally refers to the inorganic compound TiH 2 and related nonstoichiometric materials.

氢化钛，又名二氢化钛，是一种无机化合物，化学式为TiH2，为灰色粉末，溶于无水乙醇、乙醚、苯及氯仿，主要用于制造粉末钛，也可用于焊接，还可作为聚合反应的催化剂。

它可以由氢气与金属钛直接反应获得。300℃以上时，金属钛能可逆地吸收氢，最终形成化学式为TiH 2 的化合物。如果加热到1000℃以上，氢化钛将完全分解为钛和氢气。

TiH2是一种具有金属外观的灰色粉末，存在两种变体，转化温度为37℃。 低温稳定态为面心四方晶系，晶格常数为a＝0．4528nm，c＝0．4279nm。 ＞37℃为正方晶系，晶格常数a＝0．4454nm。

Titanium(II) hydride (TiH 2) is a non-stoichiometric compound that can be used in the enhancement of fracture by localized plastic deformation and brittle fracture for titanium and titanium alloy.It can be used in the hydrogen evolution and hydrogen storage. It can also be used in the foaming of aluminum due to its decomposition temperature …

TiH2 is Fluorite structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Ti2+ is bonded in a body-centered cubic geometry to eight equivalent H1- atoms. All Ti–H bond lengths are 1.92 Å. H1- is bonded to four equivalent Ti2+ atoms to form a mixture of corner and edge-sharing HTi4 tetrahedra.

2025年2月3日 · The formation of TiH 2 is particularly effective in enhancing the activation and hydrogen storage properties of the materials, reducing hydrogen absorption and desorption hysteresis. Moreover, the Mg 90 Ni 10 –5Ti composite demonstrates superior hydrogen storage properties compared to Mg 90 Ni 10 , particularly at lower temperatures.

2016年6月15日 · To enhance the T c in transition metal hydrides such as TiH 2, will likely require manipulating the electronic structure via pressure, doping or replacing Ti with other transition metal ions to...

2003年9月15日 · Studies on dehydrogenation of fine titanium hydride are important for several applications such as thermohydrogen processing of Ti and Ti based alloy components, hydrogen storage materials and bonding of metals and ceramics using TiH 2.

TiH2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Ti2+ is bonded in a 9-coordinate geometry to nine H1- atoms. There are a spread of Ti–H bond distances ranging from 1.90–2.10 Å. There are two inequivalent H1- sites.
