Abstract

Silicon nitride (Si₃N₄) has attracted substantial interest because of its extreme chemical and physical properties, but the sintering densification of Si₃N₄ is difficult, and it is easily oxidized in the high-temperature air to impact high-temperature strength, which restricts its applied range. In order to decrease the oxidization and improve the strength of Si₃N₄ at high temperature, the surface of Si₃N₄ is coated with Al(OH)₃ and Y(OH)₃ to synthesis Si₃N₄@Al(OH)₃–Y(OH)₃ core-shell composite particles. Through TEM, XRD, and BET analysis, when pH is about 9, Si₃N₄@Al(OH)₃–Y(OH)₃ core-shell composite particles are successfully synthesized by co-precipitation methods. Coating layer is about 200 nm, which is compaction and conformability. Dispersion of coated Si₃N₄ with Al(OH)₃ and Y(OH)₃ particles are very good. Synthesis of Si₃N₄@Al(OH)₃–Y(OH)₃ core-shell composite powder will lay the foundation for preparing high-performance YAG/Si₃N₄ multiphase ceramic materials.
