An extraction of 95% pure titanium was achieved by Lars Fredrik Nilson and Otto Petterson. To achieve this they chlorinated titanium oxide in a carbon monoxide atmosphere with chlorine gas before reducing it to titanium metal by the use of sodium. [64]
Titanium tetrachloride was found to reduce with hydrogen at high temperatures to give hydrides that can be thermally processed to the pure metal. With these three ideas as background, Kroll in Luxembourg developed both new reductants and new apparatus for the reduction of titanium tetrachloride. Its high reactivity toward trace amounts of water ...
A process for electrochemical production of titanium through the reduction of titanium oxide in a calcium chloride solution was first described in a 1904 German patent, [1] [2] [3] and in 1954 U.S. patent 2845386A was awarded to Carl Marcus Olson for the production of metals like titanium by reduction of the metal oxide by a molten salt reducing agent in a specific gravity apparatus.
The titanium produced by the Hunter process is in the form of powder called sponge fines. This form is useful as a raw material in powder metallurgy. The main limiting factor for the usefulness of the Hunter process is the difficulty of separating the produced NaCl from the titanium.
Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied. The field is a materials science, covering all aspects of the types of ore, washing, concentration, separation, chemical processes and extraction of pure metal and their alloying to suit various applications, sometimes for direct ...
What: Shares of Titanium Metals (NYS: TIE) , also known as Timet, soared a whopping 42% today after jet engine castings maker Precision Castparts (NYS: PCP) agreed to buy the titanium melted and ...
Ukraine's rare earth metals. Rare earths are a subset of critical minerals; there are 17 of them, and not one is a common word. For example, ytterbium and promethium are rare earths. Rare earths are important for many kinds of technology and electronics, including medical care, military, aerospace as well as clean energy uses.
