page 1 1 reprocessing silicon carbide inert matrix fuels by using a molten salt reaction/dissolution method by ting cheng a dissertation presented to the graduate school of the university of florida in partial fulfillment of the requirements for the degree of doctor of philosophy university of florida 2010
The maximum density of the silicon carbide ceramics produced by experiments was 3.16 g/cm3 (relative density 98.75%) and the maximum compressive strength was 550 MPa. The results show that the pressureless sintering process of silicon carbide with appropriate content of C+B4C sintering aids is simple and easy to control.
Silicon carbide is a widely used refractory ceramic material that can retain its mechanical properties at high temperature (~1800 °C). Often, its high temperature application is limited by the recession of the material upon oxidation.
Feb 23, 2007 · HALSIC is the name of four exceptional high performance ceramics from the silicon carbide (SiC) material group made by W. HALDENWANGER.
