The preferred ratio on a weight basis of magnesium to calcium is between about 1.2:1 to about 3.0:1. A method of refining a lead bath with the novel alloy is disclosed which provides a high recovery ratio of impurities present therein.
Magnesium - Wikipedia
Magnesium is a chemical element with the syol Mg and atomic nuer 12. It is a shiny gray solid which bears a close physical reselance to the other five elements in the second column (group 2, or alkaline earth metals) of the periodic table: all group 2 elements have the same electron configuration in the outer electron shell and a similar crystal structure.
About die casting and alloys with Pace Industries | Pace
Aluminum and magnesium alloys are considered to be moderate melting point alloys, being cast in the 1150°F to 1300°F (621°C to 704°C) range. Copper alloys are considered to be high melting point alloys, over 1650°F (899°C). Low melting point alloys are cast in hot chaer machines.
Magnesium oxide | Podcast | Chemistry World
Because of its high melting point, magnesium oxide finds many uses which apply its refractory properties, so it can be used as a furnace lining and in crucibles. It is also used for fireproofing boarding for panelling walls. Being a metal oxide, magnesium oxide is basic.
