The instant invention relates to a process for the preparation of titanium metal from an ore comprising titanium oxides which process comprises the steps of fluorinating the ore to convert the titanium oxides to titanium fluorides and then reducing the titanium fluorides to the metal. Such reduction may be carried out by contacting the titanium fluorides as a molten salt mixture with a molten alloy of zinc and aluminum at conditions whereby titanium is converted into a titanium-zinc alloy and the aluminum is converted into fluorides of aluminum. The titanium zinc alloy is separated from the fluorides of aluminum and the zinc is distilled from the alloy to leave behind titanium sponge. The ore may be an ilmenite ore and the fluorination may be carried out by contacting said ilmenite ore with a fluosilicate salt such as sodium fluosilicate.

The instant invention relates to a process for the preparation of titanium dioxide from an ore comprising titanium oxides which comprises the steps of fluorinating said ore to convert the titanium oxides to titanium fluorides; and, contacting said titanium fluorides with an alkaline material at conditions whereby said titanium fluorides are converted to titanium dioxide. The ore may be an ilmenite ore and the fluorination may be carried out by contacting said ilmenite ore with a fluosilicate salt as sodium fluosilicate.

Process for making titanium oxide from titanium ore

Anodes for current generating cells having good corrosion resistance, voltage stability and long life, especially in primary current generating cells, are described. The anodes comprise an anode composition having from about 20 to about 90 weight percent of the first constituent selected from the group consisting of iron and silicon and at least about 10 weight percent of a second constituent different from the first constituent and selected from the group consisting of molybdenum, tungsten, vanadium, niobium, titanium, phosphorus, and silicon. Anode compositions containing iron and a second constituent other than silicon may also contain up to about 10 weight percent silicon.
