Microstructure and properties of porous silicon nitride ceramics prepared by gel-casting and gas pressure sintering

Fabrication and properties of graphene reinforced silicon nitride composite materials

“…However, because of the intrinsic brittleness of ceramic materials, it is crucial to improve the strength and toughness of silicon nitride ceramics to make them more reliable for engineering applications [1][2][3][4][5][6]. Reinforcing ceramic materials with appropriate nanofillers will significantly improve their strength and toughness, as well as electrical and thermal properties.…”

Pore morphology designs of porous Si3N4-based ceramics using Si3N4 and Al2O3 poly-hollow microspheres as pore-forming agents

“…3(e)), thus the self-toughening effect achieved through crack bridging and crack deviation of the rod-like β-Si 3 N 4 grains in SN-SN [14,15] could account for their good fracture toughness.…”

Microstructure and properties of the Si3N4/silica aerogel composites fabricated by the sol–gel method via ambient pressure drying

“…To obtain excellent wave-transparent ability, the dielectric constant and loss tangent of the materials must be no more than 4.0 and 0.01, respectively [34]. Fig.…”
