Abstract
Non-pyrophoric polymethylsilane (PMS) SiC precursors allow for preparation of dense phase pure SiC with 1:1 stoichiometry. Sintering aids may be readily and reproducibly incorporated into the hyperbranched PMS. The PMS has rheology suitable for the preparation of films, coatings, fibers, and for processes such as joining and ceramic infiltration densification.
