Spinel-Si3N4: multi-anvil press synthesis and structural refinement.
In: Advanced materials, 12 (12)
Artikel, Bibliographie
Kurzbeschreibung (Abstract)
The third known polymorph of silicon nitride, which is cubic and was only recently discovered, has been prepared from two further, different precursors—Si2N2(NH) and a-Si3N4—in a high-pressure, high-temperature synthesis using multi-anvil presses. The synthesis and characterization of the products is described, which included a structural determination by Rietveld refinement of powder X-ray diffraction data. Spinel-type c-Si3N4 is significantly harder than the α and β phases and may possibly find applications as an ultrahard material.
