Late formation of silicon carbide in type II supernovae | …

We have found that individual presolar silicon carbide (SiC) dust grains from supernovae show a positive correlation between 49Ti and 28Si excesses, which is attributed to the radioactive decay of the short-lived ( t ½ = 330 days) 49V to 49Ti in the inner highly 28Si-rich Si/S zone. The 49V-49Ti chronometer shows that these supernova SiC dust grains formed at least 2 years after their parent

This high-temperature treatment leads to the formation of cubic beta silicon carbide, which differs from the well-known alpha silicon carbide in certain important aspects. Not only is the crystallographic structure different (hexagonal in case of alpha versus cubic in case of Beta SiC), but also properties effected by the atomic lattice like fracture and wetting characteristics.
