Structural Evolution of Silicon Carbide Nanopowders …
That is, threshold character of silicon carbide nanopowder sintering is associated with specificity of its hexagonal cell structure. It is possible to avoid these difficulties by applying a set of measures aimed at suppression of rapid growth, such as a significant decrease in the rate of temperature rise in the vicinity 2080°C or doping of grain boundaries by a small amount of corresponding
Microstructural control of silicon carbide via liquid phase …
Silicon carbide ceramics with various microstructures were fabried by controlling the amount and composition of a Y2O3-Al 2O3 liquid phase, crystallographic phase of the starting powders, trace impurities in those powders, and time and temperature of sintering and post- sintering heat-treatments. Alpha and beta SiC "seeds" were used to control grain growth during sintering. The grain size

Reaction bonded silicon carbide - Wikipedia
Due to the left over traces of silicon, reaction bonded silicon carbide is often referred to as siliconized silicon carbide, or its abbreviation SiSiC. If pure silicon carbide is produced by sintering of silicon carbide powder, it usually contains traces of chemicals called sintering aids , which are added to support the sintering process by allowing lower sintering temperatures.
