After the addition of TiCl4 to the strontium-nitrate solution, the pH was raised with sodium hydroxide to a value between 8 and 9 where strontium hydroxide and titanium hydroxide precipitated.
Meanwhile, the titanium complexes could precipitate as the highly dispersed crystalline hydroxide phase.
Using higher weight ratios, fumed silica, titanium dioxide and precipitated calcium carbonate accelerate moderately the hydration.
For the first time ever, atomic-scale direct observation of deuterium atoms trapping at nano-sized titanium carbide (TiC) precipitates in steel was successfully achieved using atom probe tomography (APT).
The H2O2 titanium complex formed by reaction of tissue H2O2 with titanium tetrachloride was precipitated using concentrated ammonia solution.
TBOT was dissolved in ethanol under continuous stirring following by the addition deionized water dropwise into the solution until no more white precipitate of titanium hydroxide was produced.
At 300 °C, most scandium atoms partition within one day to the precipitates, whereas titanium atoms, even after 64 days of aging, remain predominantly in solid solution in the matrix, resulting in precipitates with average composition Al3(Sc0.94Ti0.06).
This paper discusses the structural and compositional changes at the nanometer scale associated with the nucleation and growth of α precipitates in the β titanium alloy Ti-5553 (Ti–5Al–5Mo–5 V–3Cr–0.5Fe) with ω precipitates acting as heterogeneous nucleation sites.
