Titanium sponge

Titanium was discovered in England towards the end of the 18th century. Due to the high affinity of oxygen, nitrogen and carbon for titanium, a complicated and cost-intensive process is necessary. Pure titanium was only produced for the first time in the early 20th century thanks to an invention by William J. Kroll, the so-called Kroll process, which reduces titanium tetrachloride with the help of magnesium to 99.9% titanium, which is the basis for commercial production.

With a share of 0.41% by weight of the Earth's crust, titanium is the 10th most abundant element therein and is to be found in minerals such as ilmenite, rutile, titanates and iron ores. The largest deposits are located in Australia, Scandinavia, North America and in the Urals.

Titanium has the atomic number 22 in the periodic table and a density of 4.5 g/cm³. The silver-coloured transition metal has a melting point of 1,668 °C and a boiling point of 3,287 °C. High-purity titanium in powder form is a hazardous substance.

Due to its outstanding properties, e.g. high corrosion resistance, low density and low thermal expansion coefficient, titanium is used not only in the aerospace industry, but also in medicine and the sports sector. Titanium dioxide contains the colour pigments responsible for the white in ceramics, paper, plastic and toothpaste. Titanium sponge is used as alloying element for many products.

We supply titanium sponge in grain sizes of 0.16 to 70 mm with a titanium content of up to 99.74% according to Russian standards in drums under a protective argon atmosphere.
