Effect of nitrogen gas pressure during heat treatment on the morphology of silicon nitride fibers synthesized by carbothermal nitridation

Journal of Asian Ceramic Societies, 2018
The effects of N2 gas pressure on the diameter and morphology of Si3N4 fibers obtained via carbothermal nitridation were investigated. Sol–gel-derived precursors containing a silica and carbon mixture were placed in an Al2O3 crucible and heat-treated ...

Synthesis and characterization of nanostructured Mo2C on carbon material by carbothermal hydrogen reduction

, 2002
Nano-structured beta-Mo2C on ultrahigh surface area carbon material (>3000 m(2)/g) was prepared by carbothermal hydrogen reduction method. The MoO3 precursor and Mo2C have been characterized by X-ray diffraction, nitrogen adsorption, high-resolution ...

SiC synthesis using domestic mineral resources [PDF]

Processing and Application of Ceramics, 2011
The possibility of using domestic Mg-silicate (sepiolite, white) as Si source and novolac resin (as carbon source), for synthesis of fine β-SiC powder at relatively low temperatures (1673−1873 K), was demonstrated.

Reaction-rate-limiting steps in carbothermal reduction processes

, 1985
The production of ß-sialon (Si3A1303N5) and nonoxidic powders by carbothermal reduction of oxides is discussed. Special attention is paid to the rate-determining steps in the conversion process performed in a packed-bed reactor.
