The chemistry and the compounds show more similarity to those of tungsten than that of chromium.

Uvarovite Uvarovite is a calcium chromium garnet with the formula Ca3Cr2(SiO4)3.

Variations in 53Cr 52Cr and Mn Cr ratios from several meteorites indicate an initial 53Mn 55Mn ratio that suggests Mn Cr isotopic composition must result from in situ decay of 53Mn in differentiated planetary bodies.

The city serves as a distribution centre for such minerals as copper, cobalt, zinc, tin, and coal.

The headstock (1) contains the metal machine heads (1.1), which use worm gear for tuning.

OK, currently there are 45,000 people a month dying in the Congo, as a consequence of the war there over coltan and diamonds and other things.

Uganda has substantial natural resources, including fertile soils, regular rainfall, and sizeable mineral deposits of copper and cobalt.

The isotopes of cobalt range in atomic weight from 50 u (50Co) to 73 u (73Co).

This reaction does not involve the whole cobalt 60 nucleus, but affects only one of its 33 neutrons.

An example is the instability of molybdenum(III) and tungsten(III) compounds as compared with the stability of the chromium(III) compounds.

Like chromium and some other transition metals, molybdenum is able to form quadruple bonds, such as in Mo2(CH3COO)4.

There also exist chemically peculiar stars that show unusual abundances of certain elements in their spectrum especially chromium and rare earth elements.

High carbon stainless steel is stainless steel with a higher amount of carbon, intended to incorporate the better attributes of carbon steel and stainless steel.

There he used electrolysis to produce pure metals, such as chromium, magnesium, aluminum, manganese, sodium, barium, calcium and lithium.

One case occurred at Yanango where a radiography source was lost, also at Samut Prakarn a phosphorus teletherapy source was lost and at Gilan in Iran a radiography source harmed a welder.

Copper Copper can be extracted using hydroxyoximes as extractants, a recent paper describes an extractant that has a good selectivity for copper over cobalt and nickel.

In late 1971, the Duke, who was a smoker from an early age, was diagnosed with throat cancer and underwent cobalt therapy.

On February 19, 1937, a Royal Decree issued by Queen Wilhelmina finally laid down the red, white and blue colours as the national flag (heraldic colours of bright vermilion, white and cobalt blue).

For this process, Hugh Taylor of Princeton developed a platinum on carbon catalyst for the first three stages while Urey developed a nickel chromia one for the fourth stage tower.

In this hydrogen intensive process, toluene is mixed with hydrogen, then passed over a chromium, molybdenum, or platinum oxide catalyst at 500 600 C and 40 60 atm pressure.

The second decision was to occasionally ignore the order suggested by the atomic weights and switch adjacent elements, such as tellurium and iodine, to better classify them into chemical families.

The American Deluxe Telecaster (introduced in 1998 upgraded in 2004, 2008, and 2010) features a pair of Samarium Cobalt Noiseless pickups and the S 1 switching system.

The riffs to I Still Haven't Found What I'm Looking For and With or Without You also prominently use delay, with Bono likening the guitar hook from the former track to chrome bells .

By the early 19th century, synthetic and metallic blue pigments had been added to the range of blues, including French ultramarine, a synthetic form of lapis lazuli, and the various forms of Cobalt and Cerulean Blue.

One example of a nickel based niobium containing superalloy is Inconel 718, which consists of roughly 50 nickel, 18.6 chromium, 18.5 iron, 5 niobium, 3.1 molybdenum, 0.9 titanium, and 0.4 aluminium.

Plutonium gallium cobalt alloy (PuCoGa5) is an unconventional superconductor, showing superconductivity below 18.5 K, an order of magnitude higher than the highest between heavy fermion systems, and has large critical current.

According to some estimates, Kazakhstan has the second largest uranium, chromium, lead, and zinc reserves, the third largest manganese reserves, the fifth largest copper reserves, and ranks in the top ten for coal, iron, and gold.

The Soviet Union provided material support to Germany in the war effort against Western Europe through a pair of commercial agreements, the first in 1939 and the second in 1940, which involved exports of raw materials (phosphates, chromium and iron ore, mineral oil, grain, cotton, and rubber).

Even a relatively small amount of material such as cobalt 60 used in radiotherapy could cause serious harm if combined with conventional explosives in a so called dirty bomb (or otherwise deliberately used to expose the public to dangerous radiation).

Armaments Tungsten, usually alloyed with nickel and iron or cobalt to form heavy alloys, is used in kinetic energy penetrators as an alternative to depleted uranium, in applications where uranium's radioactivity is problematic even in depleted form, or where uranium's additional pyrophoric properties are not required (for example, in ordinary small arms bullets designed to penetrate body armor).
