Extinct Technetium in Silicon Carbide Stardust Grains

Jan 30, 2004· The isotopic composition of ruthenium (Ru) in individual presolar silicon carbide (SiC) stardust grains bears the signature of s -process nucleosynthesis in asymptotic giant branch stars, plus an anomaly in 99Ru that is explained by the in situ decay of technetium isotope 99Tc in the grains. This finding, coupled with the observation of Tc spectral lines in certain stars, shows that the

Silicon Carbide Abrasive Grain, Grits, & Powders

Silicon Carbide has a lower hardness and abrasive capacity than industrial diamond and boron carbide. Yet because of its much lower cost when compared with diamond or B4C, it is widely used for grinding nonferrous materials, finishing tough and hard materials, as well as filling up ceramic parts.
