The compound can also be prepared by direct reaction of tantalum metal with ethanol, in which case the overall equation is the same as that shown above for the electrochemical approach. [8] Since the 1970s, Bayer of Germany had been producing tantalum(V) ethoxide in Leverkusen, however following the break-up of Bayer, production moved to Heraeus.
Tantalum pentachloride can be prepared by reacting powdered metallic tantalum with chlorine gas at between 170 and 250 °C. This reaction can also be performed using HCl at 400 °C. [4] 2 Ta + 5 Cl 2 → 2 TaCl 5 2 Ta + 10 HCl → 2 TaCl 5 + 5 H 2. It can also be prepared by a reaction between tantalum pentoxide and thionyl chloride at 240 °C
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
Tantalum is a chemical element; it has symbol Ta and atomic number 73. It is named after Tantalus, a figure in Greek mythology. [11] Tantalum is a very hard, ductile, lustrous, blue-gray transition metal that is highly corrosion-resistant.
Tantalum pentoxide, also known as tantalum(V) oxide, is the inorganic compound with the formula Ta 2 O 5. It is a white solid that is insoluble in all solvents but is attacked by strong bases and hydrofluoric acid. Ta 2 O 5 is an inert material with a high refractive index and low absorption (i.e. colourless), which makes it useful for coatings ...
Tantalum(III) chloride or tantalum trichloride is non-stoichiometric chemical compound with a range of composition from TaCl 2.9 to TaCl 3.1 [2] Anionic and neutral clusters containing Ta(III) chloride include [Ta 6 Cl 18] 4− and [Ta 6 Cl 14](H 2 O) 4. [3] Structure of edge-capped octahedral clusters such as Ta 6 Cl 18 2−. [4]
Tantalum(IV) sulfide is an inorganic compound with the formula Ta S 2. It is a layered compound with three-coordinate sulfide centres and trigonal prismatic or octahedral metal centres. [ 2 ] It is structurally similar to molybdenum disulfide MoS 2 , and numerous other transition metal dichalcogenides .
