Technology Research of Silicon Carbide by Extruding
The silicon carbide was extruded by the batch and sintered under Nitrogen atmosphere using phenolic resin as the main organic plasticizer. The effect of phenolic resin contents on plasticity of the batch, extrusion force and density of the green bodies and the effect of the solidifying law on mechanical properties of products were studied in this paper. The results are as follows: The density and bending strength of sintered bodies reach 3.11 g/cm3 and 320Mpa with 13.6wt% plasticizer content, the extrusion moding can significantly improve the production efficiency and properties of silicon carbide ceramic.
