Lanthanum: geological information Lanthanum: geological information. Lanthanum is never found in nature as the free element. Lanthanum is found in the ores monazite sand [(Ce, La, etc.)PO 4 ] and bastn°site [(Ce, La, etc.)(CO 3)F], ores containing small amounts of all the rare earth metals. Other ores include allanite. It is difficult to separate from other rare earth elements.

Facts About Lanthanum Lanthanum is found in rare-earth minerals such as cerite, monazite, allanite, and bastnasite. Monazite and bastnasite are principal ores in which lanthanum occurs in percentages up to 25 percent and 38 percent respectively. Misch metal, used in making lighter flints, contains about 25 percent lanthanum. The availability of lanthanum and other rare earths has improved greatly in recent years. The metal can be produced by reducing the anhydrous fluoride with calcium.

Tungsten Statistics and Information Tungsten (W) is a metal with a wide range of uses, the largest of which is as tungsten carbide in cemented carbides.Cemented carbides (also called hardmetals) are wear-resistant materials used by the metalworking, mining, and construction industries.ungsten is also used to make heavy metal alloys for armaments, heat sinks, and high-density applications, such as weights and counterweights; superalloys for turbine blades; tool steels; and wear-resistant alloy parts and coatings. Tungsten composites are used as a substitute for lead in bullets and shot.

Trihalomethane Trihalomethanes (THM s) are chemical compounds in which three of the four hydrogen atoms of methane (CH 4) are replaced by halogen atoms. Many trihalomethanes find uses in industry as solvents or refrigerants. THMs are also environmental pollutants, and many are considered carcinogenic. Trihalomethanes with all the same halogen atoms are called haloforms. Several of these are easy to prepare through the haloform reaction.

Lanthanum Lanthanum oxide is a white solid that can be prepared by direct reaction of its constituent elements. Due to the large size of the La3+ ion, La2O3 adopts a hexagonal 7-coordinate structure that changes to the 6-coordinate structure of scandium oxide (Sc2O3) and yttrium oxide (Y2O3) at high temperature.

Tantalum: uses Tantalum wires were those used first for light bulbs (now tungsten is preferred). The metal is immune to body liquids and the body tolerates the metal well. Therefore, tantalum has widespread use for surgical use. For instance, it can be used in sutures and as cranial repair plates. The metal is used in the electronics industry for capacitors. The oxide is used to make special glass with a high index of refraction for camera lenses.
