Study of Zirconium and Hafnium Separation by ...
It was observed that separation of zirconium and hafnium is favored by high acidities, but considering that this is a very drastic condition, it is necessary to evaluate in what way the acidity influences the Zr/Hf separation, in other to better understand the system and to seek a way to decrease the acidity of the process. According to the results presented above, we chose to continue these ......

Sample Preparation Guides
Zirconium and hafnium metals, like titanium, are hard and resistant to corrosion. These metals resemble stainless steel in appearance with melting points of 1855 and 2222 °C respectively. Heating zircon sand in the presence of graphite in an electric furnace forms the carbides. The ZrC (zirconium carbide) that's produced is reacted with chlorine to produce ZrCl 4. The tetrachloride is reduced ......
192 ZIRCONIUM AND HAFNIUM
Zirconium and hafnium are typically contained in zircon at a ratio of about 36 to 1. Zirconium chemicals were produced by the metal producer in Oregon and by at least 10 other companies. Ceramics, foundry sand, opacifiers, and refractories are the leading end uses for zircon. Other end uses of zircon include abrasives, chemicals (predominantly, zirconium basic sulfate and zirconium oxychloride ......

Titanium, Zirconium and Hafnium
· The former is a black sandy material mined in Canada, the USA, Australia, Scandinavia and Malaysia, while the latter is mined principally in Australia. Zirconium's main minerals are zircon (ZrSiO 4) and baddeleyite (ZrO 2) mined mainly in Australia, the Republic of S. Africa, USA and the former USSR and invariably containing hafnium, most commonly in quantities around 2% of the ....
ZIRCON: A REVIEW, WITH EMPHASIS ON WEST COAST .

The future of the zirconium metal industry appears to be good because of increased use of the metal for nuclear propul sion and powergenerating plants. INTRODUCTION This comprehensive study of zircon appraises the resource and market potential of the Pacific Northwest States, Alaska, and ......
Compositional characterization of hafnium recovered from ...
· Hafnium does not exist freely in nature and is found to be always associated with zirconium ores such as Zircon sand (ZrSiO 4) or Baddeleyite (ZrO 2) . Zirconium ores contain up to 1–2% hafnium. Zirconium has very less neutron absorption crosssection and therefore it is used as cladding for nuclear fuel and as various structural components in the nuclear reactor cores, as such Zr ....
EXTRACTION OF ZIRCONIUM FROM ZIRCON. (A NEW PROCESS)
for zirconium and hafnium in TBP solvent extraction, it is desirable to reduce the silica contents in nitrate solution prepared from t caustic fritting, to less than 1000 ppm'. Although much of o silica is reported to be removed during the direct dissolution of the frit in hot concentrated nitric acid. Silica floe so produced was found to be in such a colloidal state that the filtration of the ......
Zircon | Geoscience Australia
Zircon contains the metals zirconium and hafnium. Zirconium is extremely hard and resistant to corrosion so is used to make pipes for harsh chemicals, nuclear reactor cladding, heat exchangers and speciality alloys. Zirconium is found in computer disc drives, in lightweight clothing and in many domestic products such as ballpoint pens and wearresistant knives. Hafnium is used in nuclear ......

Zirconium and hafnium
Zirconium and hafnium are corrosionresistant metals that are widely used in the chemical and nuclear industries. Most zirconium is consumed in the form of the main ore mineral zircon (ZrSiO4, or as zirconium oxide or other zirconium chemicals. Zirconium and hafnium are both refractory lithophile elements that have nearly identical charge, ionic radii, and ionic potentials....
Industrial Production of Zirconium Oxide Essay
· The zirconium sand consists of zirconium and hafnium whose properties are almost similar. Special separation techniques of precipitation, filtration and calcination are applied to separate the two products (Dhanaraj Govindhan 444). The production of zirconium oxide is broken down into three simple steps; extraction of zirconium sand, removal of wastes (including hafnium) and conversion of ......
