The processes occurring during the early stages of the formation of crystalline solids are not
well understood thus preventing the rational synthesis of new solids. The investigation of the …

Textured silicon nitride (Si 3 N 4) has been intensively studied over the past 15 years
because of its use for achieving its superthermal and mechanical properties. In this review …

Whisker-reinforced ceramic matrix composites (CMCs) are the emerging materials for
structural applications that can work at temperature above 1500° C, for example in next …

Si3N4 nanowires and SiO2 amorphous nanowires with diameters of 10–70 and 10–300nm,
respectively, have been synthesized by heating Si powders or Si/SiO2 mixtures with or …

Intermetallic compounds in the Al–Ni system were prepared by Self-propagating high-
temperature synthesis (SHS). The front high speed in the range of 1–100mm/s–typical of …

Abstract Porous Si 3 N 4/SiC ceramics were prepared with Si and SiC as raw materials, Y 2
O 3 as sintering additive and ZrO 2 as nitrided catalyst through a rapid nitration process. The …

This paper details a sustainable process for synthesizing green Si3N4 nanowires (NWs)
from high volume fractions of electronic waste (e-waste). Obsolete computers were manually …

Die Prozesse, die in den frühen Stadien der Bildung kristalliner Feststoffe ablaufen, sind nur
wenig verstanden, sodass eine rationale Synthese neuer Feststoffe weitgehend …

Large-scale ultra-long (even up to several centimeters) α-Si3N4 nanowires have been
prepared using N2 as the nitrogen source, SiO or a mixture of Si and SiO2 as the silicon …

This paper presents results of combustion synthesis (SHS) of Si3N4 from silicon powders
under nitrogen pressure (Pnitrogen= 10 MPa). The role of different additives, such as …
