20/5/2014· Tersoff functions are also known to poorly predict the melting point of silicon, which was later refined by an adjustment of three parameters of this potential []. To overcome another limitation of the poor description of the dimer properties of silicon by Tersoff, another potential function has been proposed that is an analytical bond order potential (ABOP) of almost the same formalism [ 64 ].

Density of Glass - The Physics Factbook

The range of melting points for glass, depending on its composition, is 500 to 1650 C. Glass is a poor conductor of heat and electricity and is therefore used as an insulator. The density of glass varies with each type and ranges from 2000 to 8000 kg/m 3 (for comparison, from less dense than aluminum to more dense than iron) at standard conditions.

Article: Melting temperature ranges for stainless steels

Pure iron (Fe) has a fixed melting point of 1535 C, chromium (Cr) 1890 C and nickel (Ni) 1453 C compared to a range of 1400-1450 C for type 304 stainless steel. Significance of melting ranges Melting ranges are very important to the steelmakers as the success of the melting and casting operations depends on the correct selection of temperature.
