Exempel på hur man kan använda VANADIUM i en mening

• These enzyme complexes are encoded by the Nif genes (or Nif homologs) and contain iron, often with a second metal (usually molybdenum, but sometimes vanadium).
• It is a group 5 element, along with vanadium and niobium, and it always occurs in geologic sources together with the chemically similar niobium, mainly in the mineral groups tantalite, columbite and coltan.
• Spanish-Mexican scientist Andrés Manuel del Río discovered compounds of vanadium in 1801 by analyzing a new lead-bearing mineral he called "brown lead".
• Sefström was a student of Berzelius and, when studying the brittleness of steel in 1830, he rediscovered a new chemical element, to which he gave the name vanadium.
• 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)).
• In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur, and excess carbon (the most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon, and vanadium are added to produce different grades of steel.
• Vanadinite occurs as a secondary mineral in the oxidized zone of lead-bearing deposits; the vanadium is leached from wall-rock silicates.
• Trace metals within the human body include iron, lithium, zinc, copper, chromium, nickel, cobalt, vanadium, molybdenum, manganese and others.
• Tanzanite is the blue and violet variety of the mineral zoisite (a calcium aluminium hydroxyl sorosilicate), caused by small amounts of vanadium.
• 0% manganese and small quantities of copper, nickel, niobium, nitrogen, vanadium, chromium, molybdenum, titanium, calcium, rare-earth elements, or zirconium.
• 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.
• The five elements niobium, molybdenum, tantalum, tungsten and rhenium are included in all definitions, while the widest definition, including all elements with a melting point above , such as titanium, vanadium, zirconium, and chromium.
• no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium, zirconium, or any other element to be added to obtain a desired alloying effect;.
• The four major alloying elements that form carbides in tool steel are: tungsten, chromium, vanadium and molybdenum.
• Van Arkel–de Boer process – for producing titanium, zirconium, hafnium, vanadium, thorium, or protactinium.
• He is particularly noted for early work on vanadium, photochemical studies, and his assistance in creating Oxo (food), in its earlier liquid form.
• Materials that are commonly cold extruded include: lead, tin, aluminium, copper, zirconium, titanium, molybdenum, beryllium, vanadium, niobium, and steel.
• Earth's core contains half the Earth's vanadium and chromium, and may contain considerable niobium and tantalum.
• They have been named for mythological figures, including Titans in general (titanium) and Prometheus in particular (promethium); Roman and Greek gods (uranium, neptunium, and plutonium) and their descendants (tantalum for Tantalus, a son of Zeus, and niobium for Niobe, a daughter of Tantalus); and Norse deities (vanadium for the goddess Vanadis and thorium for the god Thor).
• 01 mg/L of aluminum, iron, copper, rubidium, lithium, strontium, barium, chromium, lead, manganese, titanium, vanadium, and boron.
