Silicon burning

Silicon burns when heated in air to red heat giving silieon dioxide, Si02- Several crystalline forms of Si02 are known.

For massive red giants (M > 8 solar masses), one finds they undergo a more spectacular death cycle, with contractions, increases in temperature leading to helium burning, carbon-oxygen burning, silicon burning, and the like with the production of the elements near iron, followed by an explosive end (Fig. 12.8). 

Silicon is composed of three stable isotopes, masses 28, 29 and 30, and is one of the cornerstone elements of nucleosynthesis theory. Thermal decomposition of its nuclei after first becoming dominant in the cores of stars and its subsequent reassembly into iron-group elements is called silicon burning in stellar evolution and nucleosynthesis. That process is important for understanding how supernova explosions assemble the relative abundances of the elements having masses between... 

Ti exists primarily owing to the oxygen-burning and silicon-burning processes (both hydrostatic and explosive) of stellar nucleosynthesis in massive stars. The second... 

In the mix of interstellar atoms from which the solar system formed, 52Cr exists primarily owing to the quasiequilibrium process of stellar nucleosynthesis in explosive silicon burning. Almost all of this is produced as radioactive 52Fe, but its decay to 52Cr is complete by the end of the first day in supernova matter that is still too hot for chemistry to occur.
