Comparison of mass loss rate in reaction of silica with carbon from different investigation results

open access: yesMetalurgija, 2015
In the process of carbothermic reaction of SiO2 + mC, key reactions appear on the surfaces of both SiO2 and C grains. However, the values of these surfaces are not known. Assuming the simplest case, quartzite and carbon grains are spheres, total surfaces

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

open access: yesJournal 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 ...
