The preparation of high-purity and-quality gallium nitride nanowires is accomplished by a
catalytic growth using gallium and ammonium. A series of catalysts and different reaction …

Sol–gel route was used to prepare SiO2 xerogels containing carbon nanoparticles. Three
kinds of β-SiC nanostructures were obtained by carbothermal reduction of the xerogels …

The oxygen free Si–C fibre (Hi-Nicalon) consists of β-SiC nanocrystals (≈ 5nm) and stacked
carbon layers of 2–3nm in extension, in the form of carbon network along the fibre. This …

A novel method has been developed to produce bulk quantities of β-SiC nanowires from the
mixture of activated carbon and sol–gel derived silica embedded with Fe nanoparticles …

Preparation of β–SiC nanorods with and without amorphous SiO2 wrap** layers was
achieved by carbothermal reduction of sol-gel derived silica xerogels containing carbon …

Polymer-derived silicon carbide/silicon nitride (PDC–SiC/Si 3 N 4) composites were
prepared by additive manufacturing and infiltration technology. The composite green bodies …

The carbothermal formation of silicon carbide is studied in the case of carbon fibres coated
with a continuous silica film obtained by a solgel process. The paper discusses the influence …

The synthesis of SiC (both powder and whiskers) was carried out from rice husks with and
without the use of catalysts (iron, cobalt and nickel). The introduction of the catalyst …

The production of silicon carbide and silicon nitride whiskers in silica/carbon solid mixtures
under nitrogen-containing atmospheres was investigated. The morphology of the products …

Carbon-bonded carbon fiber (CBCF) composites are novel and important high-temperature
insulation materials owing to their light weight, low thermal conductivity and high fracture …
