Mechanisms of High-Temperature Fatigue in Silicon Carbide Ceramics

produce a composite, which is typically accomplished by incorporating continuous fibers, whiskers, platelets, or second The high-temperature mechanical properties of an in situ phase particles (3). For monolithic ceramics, in situ toughening toughened silicon carbide, with Al, B and C sintering additives can also be effective with microstructures consisting of elongated (ABC-Sic), have been exa...

Suitability of Biomorphic Silicon Carbide Ceramics as Drug Delivery Systems against Bacterial Biofilms

The present work is aimed at getting a new insight into biomorphic silicon carbides (bioSiCs) as bone replacement materials. BioSiCs from a variety of precursors were produced, characterized, and loaded with a broad-spectrum antibiotic. The capacity of loaded bioSiCs for preventing and/or treating preformed S. aureus biofilms has been studied. The differences in precursor characteristics are ma...

Silicon carbide microdisk resonator.

We demonstrate a silicon carbide (SiC) microdisk resonator with an intrinsic optical quality factor of 6.19×10(3), fabricated on the 3C-SiC-on-Si platform. We characterize the temperature dependence of the cavity resonance and obtain a thermo-optic coefficient of 2.92×10(-5)/K for 3C-SiC. Our simulations show that the device exhibits great potential for cavity optomechanical applications.
