- W2372181272 abstract "The effects of Y 2O 3, La 2O 3 and Nd 2O 3 on the mechanical properties and microstructure of Si 3N 4 ceramics were studied. The experimental results show that the mechanical properties can be improved by adding rare earth in Si 3N 4. When Y 2O 3 and La 2O 3 are both added, fracture toughness and flexural strength 7 8 MPa·m 1/2 and 962 MPa respeolively. The reason is that the rare earths added in Si 3N 4 can improve the microstructure and increase the aspect ratio of crystal grains." @default.
