Method of producing metal

A method of producing a non-metallic feedstock powder suitable for reduction to metal comprises the steps of combining a liquid with solid metal oxide particles to form a mixture, subjecting the mixture to high-shear mixing to form a liquid suspension of metal oxide and the liquid, and drying the liquid suspension using a fluidised-bed spray-granulation process to grow a plurality particles to form the non-metallic feedstock powder. The method allows feedstock powders to be grown to desired particle sizes. The method allows production of feedstock powders having controlled compositions.

Process for making zero valent titanium from an alkali metal fluotitanate

The instant invention relates to a continuous, countercurrent process for reducing an alkali metal fluotitanate salt, e.g. Na2TiF6, comprising +4 valent titanium, to zero valent titanium, in a two-step reduction process, wherein said reduction process is carried out in an adiabatic mode, and which comprises: (a) contacting said alkali metal fluotitanate, as a crystalline salt, with a first molten alloy at a reaction temperature, comprising titanium, aluminum and zinc, to reduce a portion of said +4 valent titanium to +3 valent titanium and at least 60% of the remainder to zero valent titanium and thereby melting and heating said crystalline salt to said reaction temperature, and to form a first molten salt phase comprising +3 valent titanium and an alkali metal aluminum fluoride salts, and a second molten alloy phase comprising titanium and zinc, said second molten alloy phase being immiscible with said first molten salt phase; (b) separating said first molten salt phase from said second molten alloy phase; (c) reducing said +3 valent titanium from said first molten salt phase by contacting said first molten salt phase at said reaction temperature with a third molten alloy at said reaction temperature with a third molten alloy phase at a temperature below said reaction temperature, comprising aluminum and zinc, to reduce said +3 valent titanium to zero valent titanium and thereby heating said third molten alloy phase to said reaction temperature, and to form said first molten alloy phase and a second molten salt phase, said first molten alloy phase being immiscible with said second molten salt phase; (d) separating said second molten salt phase from said first molten alloy phase; and (e) recycling said first molten alloy phase to step (a).

Production of titanium

Изобретение относится к способу получения состоящих из металлического титана или титанового сплава полуфабрикатов или готовых к использованию изделий. Способ включает электрохимическое восстановление порошков и/или гранул оксида титана и получение порошков и/или гранул металлического титана или титанового сплава в электролизере с анодом, катодом и расплавленным электролитом. При этом электролит содержит катионы металла, способного химически восстанавливать оксид титана, и хлорид-анионы. После электролиза проводят обработку порошков и/или гранул и формование полуфабрикатов или готовых к использованию изделий с концентрацией хлора по меньшей мере 100 миллионных долей. Техническим результатом является получение изделий, на которые не оказывают отрицательного воздействия уровни содержания хлора, которые оказывают влияние на рабочие характеристики, в частности свариваемость изделий, полученных другими способами. 2 н. и 21 з.п. ф-лы, 2 табл.
