Abstract A novel ZrSi 2 –MgO system was used as sintering additive for fabricating high thermal conductivity silicon nitride ceramics by gas pressure at 1900°C 12 hours. By keeping the total amount of additives 7 mol% and adjusting in range 0‐7 mol%, effect addition on behaviors were investigated. It found that binary effective densification Si 3 N 4 ceramics. XRD observations demonstrated reacted with native silica surface to generate ZrO β‐Si grains. TEM situ dilatometry confirmed formed...
A robust flame-retardant separator was fabricated by a nonsolvent-induced phase separation method incorporating polyimide with silicon nitride (Si3N4) whiskers. Compared powder-blended separators, whisker-blended separators not only suppressed the agglomeration of fillers but also improved internal connectivity separator. These advantages were conducive to boosting Li ions and improving cycling stability. The exhibited high heat endurance in air (400 °C for 1 h). Cells assembled this initial...
Abstract Binary nonoxide additives ZrSi 2 ‐MgSiN were applied to obtain Si 3 N 4 ceramics with high thermal conductivity by gas pressure sintering. The shrinkage behaviors during sintering investigated in situ dilatometry. Although densification was retarded due a higher N/O ratio the liquid phase, incorporation of oxygen inhibited because lower content phase. substitution oxide eliminated native SiO and induced nitrogen‐rich liquid, resulting purified grains, reduced glassy enhanced ‐Si...
A novel aqueous gelcasting technique was employed to prepare porous silicon nitride ceramics using water‐soluble copolymer of isobutylene and maleic anhydride (Isobam) as both dispersant gelling agent. The effects fabrication parameters, including sintering additives, the second phase ( BN ), pore‐forming agent (corn starch), on microstructure mechanical properties were separately investigated. sample with Yb 2 O 3 additive, having a porosity ~48.6%, showed high flexural strength 233 MP...
Abstract The mixed surfactants were successfully applied to fabricate the highly porous Si 3 N 4 ceramic foams by direct foaming method. oppositely charged in slurries could combined into catanionic surfactant electrostatic attraction and facilitate formation of ultra‐stable foams. microstructure foams, including pore structure, mean size, size distribution porosity tailored varying mixing ratio surfactant, concentration solid content initial slurries. with 92%‐97%, 140‐240 µm compressive...
Abstract Porous Si 3 N 4 ceramics with unidirectionally aligned channels were prepared via freezing suspension distinct solid contents under different temperatures. The samples obtained using lower content in ceramic at higher temperature exhibit larger Darcian and non‐Darcian constants due to their open porosity, pore size tortuosity. Moreover the investigation on individual contributions of viscous energy losses inertial total pressure drop during permeation process indicates that...
