Exempel på hur man kan använda COBALT i en mening

• The proportion iron:nickel is between 90%:10% and 95%:5%; small quantities of other elements, such as cobalt or carbon may also be present.
• This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc.
• The horizontal fesses are bands of equal size in the colours from top to bottom, red (officially described as a "bright vermilion"), white (silver), and blue ("cobalt blue").
• Delftware is one of the types of tin-glazed pottery or faience in which a white glaze is applied, usually decorated with metal oxides, in particular the cobalt oxide that gives the usual blue, and can withstand high firing temperatures, allowing it to be applied under the glaze.
• A cobalt bomb is a type of "salted bomb": a nuclear weapon designed to produce enhanced amounts of radioactive fallout, intended to contaminate a large area with radioactive material, potentially for the purpose of radiological warfare, mutual assured destruction or as doomsday devices.
• Prior to 2023, the law specified the colors using the cobalt blue, chrome yellow and vermilion red pigments, but did not go into further detail.
• Pyroxenes have the general formula , where X represents calcium (Ca), sodium (Na), iron (Fe(II)) or magnesium (Mg) and more rarely zinc, manganese or lithium, and Y represents ions of smaller size, such as chromium (Cr), aluminium (Al), magnesium (Mg), cobalt (Co), manganese (Mn), scandium (Sc), titanium (Ti), vanadium (V) or even iron (Fe(II) or Fe(III)).
• The ceramic stoneware of La Roche (cobalt blue pottery, glazed with salt) is a local tradition known, initiated in 1836 by Henry Hoffman, a native of Ransbach in the Duchy of Nassau.
• On top of this is the Zechstein, dating to the Permian, found in a band stretching from Sailauf to Eidengesäß and as an "island" in the area of the stream Bieber near Biebergemünd, where it contained deposits of silver, copper, iron and cobalt.
• Since the 1954 Castle Bravo thermonuclear weapon test demonstrated the feasibility of making arbitrarily large nuclear devices which could cover vast areas with radioactive fallout by rendering anything around them intensely radioactive, nuclear weapons theorists such as Leo Szilard conceived of a doomsday machine, a massive thermonuclear device surrounded by hundreds of tons of cobalt which, when detonated, would create massive amounts of Cobalt-60, rendering most of the Earth too radioactive to support life.
• Essential trace elements in human nutrition, and other animals include iron (Fe) (hemoglobin), copper (Cu) (respiratory pigments), cobalt (Co) (Vitamin B12), iodine (I), manganese (Mn), chlorine (Cl), molybdenum (Mo), selenium (Se) and zinc (Zn) (enzymes).
• Trace metals within the human body include iron, lithium, zinc, copper, chromium, nickel, cobalt, vanadium, molybdenum, manganese and others.
• SmCo (cobalt); used for permanent magnets in guitar pickups, headphones, satellite transponders, etc.
• Georg Brandt (26 June 1694 – 29 April 1768) was a Swedish chemist and mineralogist who discovered cobalt c.
• After exploration, it has been found that tungsten, tin, nickel, antimony, bismuth, antimony, cobalt, molybdenum, copper, lead and zinc, gold, silicon, coal, kaolin, limestone, fluorite, granite, monazite sand Wait for more than 20 minerals.
• Geochemical analysis of the iron, based on the ratio of iron to nickel and cobalt, confirms that the iron was meteoritic in origin.
• Stellite alloys are a family of completely non-magnetic and corrosion-resistant cobalt alloys of various compositions that have been optimised for different uses.
• He invented a time-consuming process that involved a cobalt blue base and white undercoating, which he then coated with a series of thin alternating coatings of oil and varnish.
• Its list includes—in addition to copper, lead, nickel, and zinc—the following metals: iron and steel (an alloy), aluminium, tin, tungsten, molybdenum, tantalum, cobalt, bismuth, cadmium, titanium, zirconium, antimony, manganese, beryllium, chromium, germanium, vanadium, gallium, hafnium, indium, niobium, rhenium, and thallium, and their alloys.
• With its diameter of 2 kilometers and assumed composition similar to typical iron-type meteorites, he calculated a mass of 3 (30 billion) tons and a 1996 market value of $8 trillion for its iron and nickel alone, another $6 trillion for its cobalt, and $6 trillion more for its platinum-group metals.
