With great mechanical properties, silicon carbideceramics have been used in many fields. But the using way are limited because of the brittleness of SiC ceramics.
The reactive sintering silicon carbideceramics made by ihrigizing reaction include large quantity of silicon carbide, partial Silicon and a small amount of un-reacted carbon.
经过渗硅试验后得到的反应烧结碳化硅陶瓷中含有大量的碳化硅，以及部分的自由硅和少量的未反应的碳。

Researches on the superplasticity of advanced structural ceramics were systematically reviewed, emphasising on three kinds of ceramics:oxide ceramics, nitride ceramics and carbideceramics.
