Controlled growth of SiC crystals in combustion synthesis

Fei Li et al.

Summary: β-SiC powders with different particle morphologies were prepared by combustion synthesis using carbon black, carbon fiber, graphene, and graphite as carbon sources. The morphology of the precursor carbon source plays a crucial role in determining the particle morphology of SiC during the controlled growth process.

Fabrication and reaction mechanism of MgO-stabilized ZrO2 powders by combustion synthesis

Nan Lu et al.

Summary: In this study, MgO-stabilized ZrO2 powders were prepared by combustion synthesis. The diluent content significantly affected the combustion process and the properties of the resulting product. Increasing the diluent content led to decreases in combustion temperature, propagation velocity, and MgO content.

Combustion synthesis and spark plasma sintering of high emissivity ZrO2/graphene ceramic as imitated moxibustion emission source

Fengxia Yang et al.

Summary: This study successfully synthesized high-emissivity ZrO2/graphene composite ceramic blocks with different graphene content through combustion synthesis and spark plasma sintering. The infrared performance studies showed that the ZrO2/graphene ceramic exhibited high emissivity at room temperature and 470 degrees C, and also showed good oxidation resistance.

Synthesis and microwave absorption properties of multilayer SiC/C foam with alternating distribution of C and SiC

Bangxiao Mao et al.

Summary: A multilayer SiC/C foam structure with alternating distribution of C and SiC was successfully prepared, showing promising microwave absorbing performance. The study proposed a microwave absorbing mechanism based on the synergistic effects of multiple reflections, scattering, dipole polarization, and interface polarization in the multilayer SiC/C structure.
