Fabrication of ultrathin SiC film using grafted poly(methylsilane)

Creator:: Lertwiwattrakul, Wimol
Abstract:: β-SiC is a semiconductor for high temperature devices, which exhibits several outstanding properties such as high thermal stability, good chemical stability and wide band gap. There is a possibility of fabricating a crack-free ultrathin SiC film on silicon wafers by pyrolysis of polymethylsilane (PMS) film. This study looks into the...

Thermal Processing of Injection-Molded Silicon Carbide

Creator:: Chinn, Richard E.
Abstract:: Silicon carbide is an important and versatile nonoxide ceramic. Powder injection molding (PIM) is a method of high-speed fabrication of complex near-net shapes of SiC and other powders. Green micro-machining (GMM) is used to extend the shaping capability of green ceramics and powder metallurgy to smaller feature sizes. Debinding--removal of...

Sintering of nanocrystalline silicon carbide in plasma pressure compaction system

Creator:: Bothara, Manish G.
Abstract:: Nanostructured ceramics offer significant improvements in properties over the corresponding materials with grain sizes on the order of tens to hundreds of microns. Silicon carbide (SiC) is an important structural ceramic whose properties can potentially be enhanced due to nanoscale microstructures. It has been suggested that SiC samples with grain...

Kinetics of nano-sized Si₃N₄ powder synthesis via ammonolysis of SiO vapor

Creator:: Vongpayabal, Panut
Abstract:: An 89 mm-diameter vertical tubular-flow reactor was used to study the kinetics of nano-sized silicon nitride powder synthesis via the animonolysis of SiO vapor at temperatures ranging from 1300°C to 1400°C. The SiO generation rate was controlled by adjusting the mass of SiO particles initially charged in the SiO generator,...

A theoretical and experimental study of self-propagating high-temperature synthesis of titanium carbide

Creator:: Huque, Ziaul
Abstract:: Self-propagating high-temperature synthesis (SHS) is a new method of producing advanced ceramic materials and offers an attractive alternative to conventional methods of materials processing. An experimental investigation was carried out to determine the SHS reaction wave propagation speed in a vertical cylindrical compact made from a mixture of titanium and...

Flow characterization of multiple-tube reactors for synthesis of nano-sized silicon nitride powder via silicon monoxide ammonolysis

Creator:: Vas-Umnuay, Paravee
Abstract:: Concentrically arranged multiple-tube reactors with different dimensions were built for synthesizing nano-sized silicon nitride powder via the ammonolysis of SiO vapor. The reaction was operated at temperatures ranging from 1350 to 1400°C and pressure slightly above atmospheric pressure. Silicon monoxide (SiO) vapor was generated by charging argon gas through a...
