DOI: 10.1007/s10853-017-1823-x
Abstract: AbstractCurrent silicon melt-infiltrated (SMI) ceramic matrix composites (CMCs) are limited by the melting temperature of silicon (1414 °C) and the volatility of the thermally grown SiO2 scale in high-temperature water vapor environments. Replacement of the melt-infiltrated… read more here.
