2019-4-20 · The term “silicon carbide” is commonly used to describe a range of materials that are in fact quite distinct. Mechanical engineers may use it to describe ceramics which are fabried from relatively impure SiC crystallites bonded together with various binders under temperature and/or pressure, while electrical engineers may use the term to describe high purity single crystal wafers of SiC.
The comparatively low reaction temperature is attributed to an intimate, atomic level, mixing of Hf and carbon which is achieved by gelation of water solution of the precursors. Increase in temperature resulted in an increase in volume fraction of formed hafnium carbide. Nearly pure hafnium carbide (∼97%) was obtained at 1600 °C.
