Latest Patent Applications

Ravit Silverstein's notable patent application is titled "VAPOR-MEDIATED SYNTHESIS OF SILICON CARBIDE MATRICES FOR CERAMIC MATRIX COMPOSITES BY REACTIVE MELT INFILTRATION." This application describes a two-step synthesis of SiC, which includes the initial exposure of carbon surfaces to silicon vapor, followed by silicon melt infiltration. The application details the use of interrupted differential thermal analysis (DTA) of amorphous carbon and silicon powder mixtures, along with microstructure characterization, to identify the stages of the reaction. The exposure to silicon vapor results in a SiC layer characterized by nanoscale porosity, driven by the volume change associated with the reaction. This process forms a continuous pore network that facilitates subsequent melt access to the reaction front with carbon. The application discusses the temperature sensitivity of the vapor phase reaction and its implications for enhancing the reactive melt infiltration process and the fabrication of SiC matrices for ceramic composites.
