Structure evolution of ZrB2–SiC during the oxidation in air - Volume 23 Issue 7 - Xing-Hong Zhang, Ping Hu, Jie-Cai Han The structure evolution and oxidation behavior of ZrB 2 –SiC composites in air from room temperature to ultrahigh temperature were investigated using furnace testing, arc jet testing, and thermal gravimetric analysis (TGA).
This paper addresses certain key feasibility issues facing the appliion of SiC-matrix microencapsulated fuels for light water reactor appliion. Issues addressed are the irradiation stability of the SiC-based nano-powder ceramic matrix under LWR-relevant irradiation conditions, the presence or extent of reaction of the SiC matrix with zirconium-based cladding, the stability of the inner
A high temperature CVD-process has been developed to produce a new type of high-performance amorphous silicon-oxynitride (Si-N-O) fibres. The fibres were grown on a SiC substrate at 1450 degrees C exposing a stoichiometric precursor powder mixture of SiO2+SiC, doped with 10 wt% Ti powder …

2/3/2004· More preferably, this Si—SiC meer for heat treatment of conductor has a CVD-SiC film formed on the surface of the Si—SiC base material, wherein the content of Fe and Na in at least the area of 10 μm from the surface of the CVD-SiC film is 300 ppb or less.
The silicon reacts with the carbon forming more SiC which bonds the initial SiC particles. Sintered SiC is produced from pure SiC powder with non-oxide sintering aids. Conventional ceramic forming processes are used and the material is sintered in an inert atmosphere at temperatures up to 2000ºC or higher.
Silicon carbide (SiC), also known as carborundum / k ɑːr b ə ˈ r ʌ n d əm /, is a semiconductor containing silicon and carbon.It occurs in nature as the extremely rare mineral moissanite.Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive..
