 This paper discusses a new approach to fabricating porous silicon carbide, sick, ceramics using direct ink writing, DIW, and direct foaming methods. The authors found that the nozzle diameter plays an important role in maintaining the structure of the sick green body. Additionally, increasing the sintering temperature leads to lower porosity and higher compressive strength. The authors also observed that the porous sick ceramics have low reflection losses and good electromagnetic, EM, wave absorption capabilities. Overall, this study demonstrates the potential of combining DIW and direct foaming techniques to produce porous sick ceramics with high strength and excellent EM wave absorption characteristics.
