List of silicon producers - Wikipedia

This is a list of silicon producers.The industry involves several very different stages of production. Production starts at silicon metal, which is the material used to gain high purity silicon.High purity silicon in different grades of purity is used for growing silicon ingots, which are sliced to wafers in a process called wafering.

Late formation of silicon carbide in type II supernovae | …

Abstract We have found that individual presolar silicon carbide (SiC) dust grains from supernovae show a positive correlation between 49 Ti and 28 Si excesses, which is attributed to the radioactive decay of the short-lived (t ½ = 330 days) 49 V to 49 Ti in the inner highly 28 Si-rich Si/S zone.Si-rich Si/S zone.
