Abstract Silicon carbide (SiC) is a high-performance structural ceramic material with excellent comprehensive properties, and is unmatched by metals and other structural materials. In this paper, raw SiC powder with an average grain size of 5 upmu m was sintered by an isothermal-compression process at 5.0 GPa and 1500 ℃; the maximum hardness of the sintered samples was 31.3 GPa. Subsequently, scanning electron microscopy was used to observe the microscopic morphology of the recovered SiC samples treated in a temperature and extended pressure range of 0-1500 ℃ and 0-16.0 GPa, respectively. Defects and plastic deformation in the SiC grains were further analyzed by transmission electron microscopy. Further, high-pressure in situ synchrotron radiation x-ray diffraction was used to study the intergranular stress distribution and yield strength under non-hydrostatic compression. This study provides a new viewpoint for the sintering of pure phase micron-sized SiC particles.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
