Zirconium in a Sentence
  • Zirconium combines with sulphur to form a sulphide, and with carbon to form several carbides.
  • Carbon was joined with silicon, zirconium and titanium, while boron, being trivalent, was relegated to another group. A general classification of elements, however, was not realized by Frankland, nor even by Odling, who had also investigated the question from the valency standpoint.
  • In the same year as Klaproth detected uranium, he also isolated zirconia or zirconium oxide from the mineral variously known as zircon, hyacinth, jacynth and jargoon; but he failed to obtain the metal, this being first accomplished some years later by Berzelius, who decomposed the double potassium zirconium fluoride with potassium.
  • In the following year, 1795, Klaproth announced the discovery of a third new element, titanium; its isolation' (in a very impure form), as in the case of zirconium, was reserved for Berzelius.
  • Rosenbuschite, hiortdahlite, and some other rare members containing zirconium and fluorine, occur as accessory constituents in the nephelinesyenite of southern Norway.
  • In 1858 he pointed out the isomorphism of the fluostannates and the fluosilicates, thus settling the then vexed question of the composition of silicic acid; and subsequently he studied the fluosalts of zirconium, boron, tungsten, &c., and prepared silicotungstic acid, one of the first examples of the complex inorganic acids.
  • In its chemical relations, titanium is generally tetravalent, and occurs in the same sub-group of the periodic classification as zirconium, cerium and thorium.
  • Troost produced crystallized zirconium by fusing the double fluoride with aluminium in a graphite crucible at the temperature of melting iron, and extracting the aluminium from the melt with hydrochloric acid.
  • In its chemical affinities zirconium resembles titanium, cerium and thorium; it occurs in company with these elements, and is tetravalent in its more important salts.
  • Zirconium oxide or zirconia, Zr02, has become important since its application to the manufacture of mantles for incandescent gas-lighting.
  • Zirconium hydroxide, Zr(OH) 4, as thus obtained, is quite appreciably soluble in water and easily in mineral acids, with formation of zirconium salts, e.g.
  • Zirconium hydride, ZrH2, is supposed to be formed when zirconia is heated with magnesium in an atmosphere of hydrogen.
  • Zirconium fluoride, ZrF4, is obtained as glittering monoclinic tables (with 3H 2 0) by heating zirconia with acid ammonium fluoride.
  • Zirconium chloride, ZrC1 4, is prepared as a white sublimate by igniting a mixture of zirconia and charcoal in a current of chlorine.
  • Zirconium bromide, ZrBr 4, is formed similarly to the chloride.
  • Zirconium iodide, Zr14, was obtained as a yellow, microcrystalline solid by acting with hydriodic acid on heated zirconium (Wedekind, Ber., 1904, 37, p. 1135).
  • It fumes in air; with water it gives ZrOI 2.8H 2 0; and with alcohol ethyl iodide and zirconium hydroxide are formed.
  • Zirconium also forms double sulphates of the type Zr203(S04M)2 nH20, where M =K, Rb, Cs, and n=8 for K, 15 for Rb, 11 for Cs (Rosenheim and Frank, Ber., 1905, 38, p. 812).
  • In its salts, thorium is tetravalent, and in the periodic classification it occurs in the same sub-group as titanium, cerium and zirconium.
  • Later they find the zirconium that Roger brought home and conclude that he is the thief.
  • Victoria came on the phone and said they wanted cubic zirconium on the detailing, and a large Union Jack somewhere too.
  • It is difficult to produce because it requires very high temperatures, over 2,700 Celsius, to melt powdered zirconium and zirconium dioxide.
  • It is the oxide of the metallic element zirconium.
  • Kind to you - great for sensitive skin PitRok does not contain aluminum chlorohydrate or aluminum zirconium that many people find irritating.
  • Features abbreviated slimline EVA handle, Fuji GPS reel fitting, and Zirconium rings.
  • Zirconia Overview Zirconia is an ionic ceramic, zirconium oxide.
  • The sample was mechanically polished and mounted by means of a zirconium silicate ceramic cement.
  • Zirconium production, other than production of fuel cladding, is not subject to declaration or inspection.
  • Within four seconds, steam pressure and power readings went off the scale; the zirconium fuel assemblies and the channels containing them disintegrated.
  • The Lifetime Mother's Floral Locket is a sterling silver heart-shaped locket in a flower filigree design that has a clear zirconium crystal in the center.
  • Cubic zirconia (often abbreviated CZ) is a lab-created crystalline cubic form of zirconium oxide stabilized with small quantities of other minerals, typically yttrium or calcium.
  • Diamonds can be found in many different colors, and so can CZ, depending on what different mineral oxides have been added to the zirconium oxide during crystal stabilization and cooling.
  • Stephen Lux, President and CEO of Gemesis, a company that produces quality, lab-created diamonds explains, "Diamond-like materials such as cubic zirconium, moissanite and diamond-coated materials are not diamond.
  • If a diamond eternity ring isn't in your budget, but you like the look and don't mind purchasing a cubic zirconium, Diamonique, or colored stone eternity ring, they are out there and they are absolutely stunning.
  • Another form, aluminum zirconium tetrachlorohydrex glycine, is a more tolerable form of aluminum salt that is less likely to result in skin irritation.
  • In 1824 he obtained zirconium from potassium zirconium fluoride; the preparation of (impure) titanium quickly followed, and in 1828 he obtained thorium.
