Ferrosilicochromium-Filled Polymer-Derived Ceramics

Ferrosilicochromium-Filled Polymer-Derived Ceramics

Rectangular green bodies fabricated from a granulated mixture of polymethylsilsesquioxane (PMS), ferrosilicochromium (FeSiCr), and SiC were cross‐linked in a warm press at 240°C under a pressure of 9 MPa. The samples were then pyrolyzed at 950°C and subsequently heat treated at 1275°C in N2 atmosphe...

Zusammenfassung:Rectangular green bodies fabricated from a granulated mixture of polymethylsilsesquioxane (PMS), ferrosilicochromium (FeSiCr), and SiC were cross‐linked in a warm press at 240°C under a pressure of 9 MPa. The samples were then pyrolyzed at 950°C and subsequently heat treated at 1275°C in N2 atmosphere at pressures up to 5 MPa. For the composites with 25 vol% FeSiCr, a total linear shrinkage of
