Its melting and boiling points of 1414 °C and 3265 °C, respectively, are the second highest among all the metalloids and nonmetals, being surpassed only by boron. [a] Silicon is the eighth most common element in the universe by mass, but very rarely occurs as the pure element in the Earth's crust.
Melting point The temperature at which the solid–liquid phase change occurs. Boiling point The temperature at which the liquid–gas phase change occurs. Sublimation The transition of a substance directly from the solid to the gas phase without passing through a liquid phase. Density (g cm −3)
Melting point of Silicon is 1410°C. Note that, these points are associated with the standard atmospheric pressure. In general, melting is a phase change of a substance from the solid to the liquid phase.
The reduced bond energy in crystalline silicon renders the element lower melting, softer, and chemically more reactive than diamond. A brown, powdery, amorphous form of silicon has been described that also has a microcrystalline structure.
Properties: The melting point of silicon is 1410°C, boiling point is 2355°C, specific gravity is 2.33 (25°C), with a valence of 4. Crystalline silicon has a metallic grayish color. Silicon is relatively inert, but it is attacked by dilute alkali and by halogens.

Melting point: 1687 [1414 °C (2577 °F)] K; Boiling point: 3173 [2900 °C (5252 °F)] K; Liquid range: 1486 K ; Critical temperature: (no data) K; Superconduction temperature: (no data) K; Image showing periodicity of melting point for the chemical elements as colour-coded squares on a periodic table grid.
Silicon is prepared commercially by heating silica and carbon in an electric furnace, using carbon electrodes. Several other methods can be used for preparing the element. Amorphous silicon can be prepared as a brown powder, which can be easily melted or vaporized.
