Regular aluminum and its alloys inevitably contain impurities. An impurity can be described as any chemical elements not intentionally introduced into the alloy composition. Chemical impurities will change a the melting point temperature. This is called a melting point depression. If the melting point ...
PROBLEM TO BE SOLVED: To provide a low melting point aluminum alloy brazing filler material, wherein buckling deformation, melting or the like of a thin material such as a fin is not caused and an electric potential becomes a value between a fin and a coolant tube for holding corrosion ...
melt·ing point (mĕl′tĭng) The temperature at which a solid becomes a liquid. For a given substance, the melting point of its solid form is the same as the freezing point of its liquid form. The melting point of ice is 32°F (0°C); that of iron is 2,797°F (1,535°C...
did their behavior under extreme pressure point to a then-wild idea of a "quantum state"? more from popular mechanics related story pouring melted aluminum into a lava lamp because of this special attention to alkali metals, the brown scientists were surprised to find that the pressure-linked ...
The surface atoms, due to their low coordination, melt before the bulk atoms and hence the melting point of nanoparticles is less than that of their bulk. However, the melting behavior of clusters can be different from one element to another. While Na clusters have lower meting point than ...

melting point, temperature at which a substance changes its state from solid to liquid. Under standard atmospheric pressure different pure crystalline solids will each melt at a different specific temperature; thus melting point is a characteristic of a substance and can be used to identify it. Whe...
3.4.1 Melting point The melting range of racemic guaifenesin can be between 78°C and 82°C, and current USP specifies that the magnitude of the temperature interval spanning the beginning and end of melting cannot exceed 3°C. The latest issue of the Merck Index quotes a melting point of...
[Ken] figured out how to get around the $500 price tag of a commercial unit by building this DIY melting point test apparatus. In this image he’s using a thermocouple to monitor the temperature of the melting surface, but mentions that you can do this with an inexpensive dial thermometer...
