Improved sintering performance of β-SiAlON-SiN and its osteogenic differentiation ability by adding β-SiAlON.

To improve the sintering performance of silicon nitride bioceramics, we explored the effect of β-SiAlON's Z-value on the physical, chemical, and biological properties of β-SiAlON-SiN composites. Results showed that the phase product was β-SiN. As the Z-value increased, the X-ray diffraction peaks gradually shifted to a smaller angle, the material grains were more tightly packed, and the bulk density and compressive strength increased, reaching the highest values (2.
