“…As an efficient, effective and low cost way, combustion synthesis has been applied to prepare various inorganic products including silicon nitride [1,2], AlN [3], silicon carbide [4,5], sialon [6], intermetallic compound [7], etc. Many researches have been performed to investigate the effect of parameters on the morphology and properties of silicon nitride powders or whiskers [1,4,6,[8][9][10][11][12][13].…”

In this paper, porous silicon nitride ceramics were prepared feasibly by combustion synthesis with different glasses as additives. The results reveal that the morphology, strength and porosity are relevant to glass type. When BN is added, the porosity and strength is depended on the glass content. With the increasing glass content, the porosity of the composite decreased and the strength increased.

“…К числу активаторов спекания относится также и ZrO2. В ТНЦ СО РАН [4] получены нитридкремниевые композиты при азотировании ферросилиция (сплав «железо-кремний») с добавками циркона методом СВС. Азотирование ферросилиция сопровождается выделением тепла за счет реакции взаимодействия кремния с азотом.…”

Представлена химическая стадийность образования продуктов синтеза при СВС- азотировании смеси «40% ферросилиций – 30% азотированный ферросилиций – 30% циркон» в присутствии Al (1–10 мас.%) с использованием изотермического синтеза и дифференциальной сканирующей калориметрии. Установлено, что в процессе синтеза происходит образование AlN при взаимодействии летучих субоксидов Al с азотом; Si3N4 при взаимодействии кремния с азотом, присутствующего в составе исходного сплава и образующегося в результате плавления эвтектики FeSi2-Si, и диссоциации силицидов железа; ZrN – в результате алюминотермического восстановления ZrO2 до Zr с последующим его азотированием до ZrN.

“…Several studies have been done using these methods to fabricate Fe-Si 3 N 4 [6], Fe-Si 3 N 4 -SiC [18,19], and Fe-Si 3 N 4 -ZrO 2 [20] refractories. Results showed that, compared with their traditional rivals, Fe-Si 3 N 4 based refractories exhibit high thermal strength, a higher coefficient of thermal conductivity, and better thermal shock resistance [19].…”

Si3N4-Fe3Si composites were prepared using Fe-Si3N4 as the source of Fe3Si by gas-pressure sintering. By adding different amounts of Fe-Si3N4 into the starting powders, Si3N4-Fe3Si composites with various Fe3Si phase contents were obtained. The microstructure and mechanical properties of the composites were investigated. With the increase of Fe-Si3N4 contents, the content and particle size of Fe3Si both increased. When more than 60 wt. % Fe-Si3N4 were added, the abnormal growth of Fe3Si particles occurred and oversized Fe3Si particles appeared, leading to non-uniform microstructures and worse mechanical properties of the composites. It has been found that Fe3Si particles could toughen the composites through particle pull-out, interface debonding, crack deflection, and particle bridging. Uniform microstructure and improved mechanical properties (flexural strength of 354 MPa and fracture toughness of 8.4 MPa·m1/2) can be achieved for FSN40.
