1/1/2018· The 186W/184W ratio, however, shows no apparent deviation from the solar value. Tungsten isotopic measurements in single mainstream stardust SiC grains revealed lower than solar 182W/184W, 183W/184W, and 186W/184W ratios. We have compared the SiC data with theoretical predictions of the evolution of W isotopic ratios in the envelopes of AGB stars.

The SHS Bibliography Project - 2011 (Dominique VREL)

Coustion synthesis of beta-silicon carbide (SiC) powders was accomplished at a nitrogen pressure lower than 2 MPa. The coination of mechanical activation and chemical stimulation was effective in enhancing the reactivity of Si powder reactants, which was responsible for the reduction in the minimum nitrogen pressure normally required for the coustion synthesis of SiC.
