This is true even if the impurity is higher melting (when pure) than the major component. For example, if a chemical that normally melts at 130 C is contaminated by a small amount of material that when pure melts at 200 C, the resulting mixture will not melt between 130 C and 200 C.

chemistry.highest melting point? ? Yahoo Answers

Feb 03, 2009The melting point of a pure substance is always higher than the melting point of that substance when a small amount of an impurity is present. The more impurity is present, the lower the melting point. Eventually, a minimum melting point will be reached. The mixing ratio that results in the lowest possible melting point is known as the eutectic

What material is used to hold molten iron in a furnace?

There are two categories of materials with higher melting points, but only a few of those materials are both economical and safe. Generally, any material with a melting point high enough to withstand the melting points of commercially used metals such as iron, copper, and aluminum are called refractory materials .

Melting Points of Rocks and Minerals

Melting Points of Rocks Igneous rocks form through the crystallization of magma.There is a considerable range of melting temperatures for different compositions of magma. All the silicates are molten at about 1200C and all are solid when cooled to about 600C. Often the silicates are grouped as high, medium and low-melting point solids.
