The formation of nodules is achieved by addition of nodulizing elements, most commonly Magnesium (note Magnesium boils at 1100C and Iron melts at 1500C) and, less often not Cerium (usually in the form of Misch metal). Tellurium has also been used. Yttrium, often a component of Misch metal, has also been studied as a possible nodulizer.

Metallurgic Processes | Boundless Chemistry

An ore is a type of rock that contains minerals with important elements such as metals. Ores are extracted through mining; they are then refined to extract the valuable element(s). The grade or concentration of an ore mineral, or metal, as well as its form of occurrence, will directly affect the costs associated with mining it.

US6126713A - Additive for use in producing spheroidal

If rare earth elements and calcium are used as nodulizing elements, sulfides and/or oxides of such elements can be contained in the nucleus. As a result of further detailed study of the nucleus for the graphite spheroids, it has been found that MgO contributes as the substrate for forming MgS nucleus on which graphite grows to form graphite

Ductile iron - The Full Wiki

Ductile iron, also known as ductile cast iron, nodular cast iron, spheroidal graphite iron, spherulitic graphite cast iron [1] and SG iron, is a type of cast iron invented in 1943 by Keith Millis. [2] While most varieties of cast iron are brittle, ductile iron is much more …

Mechanical Properties of Nodular Cast Iron - EVOCD

Nodular Cast Iron, also referred to as ductile iron or spheroidal graphite iron, is a group of irons in which the graphite forms as nodules (spherical) instead of flakes as in normal cast iron. Nodulizing elements, typically magnesium, are used to allow the solidifiion of the graphite into nodules.
