研究了纤维含量和烧结温度对莫来石/羟基磷灰石复合材料烧结性能和力学性能的影响。采用水热法和无压烧结法制备了复合材料。通过水热合成，纤维的含量从5 wt %到15 wt %不等，然后在1150、1250和1350℃的温度下烧结莫来石纤维和羟基磷灰石复合粉末。随着纤维含量的增加，复合材料呈现出更加微扰的结构。此外，复合材料在高温下经历孔隙聚结，呈现致密的微观结构。x射线衍射表明复合材料经过多种化学反应生成了硅酸盐玻璃。硅酸盐玻璃的产生增加了颗粒重排的驱动力，减少了孔隙的数量，促进了复合材料的致密化。致密化通常导致硬度和抗弯强度的增加。该研究提出了致密化机制，并为这些材料的烧结性能开辟了新的见解。
The effect of fiber content and sintering temperature on sintering behavior and mechanical properties of mullite fibers/hydroxyapatite composites was studied. The composites were fabricated by hydrothermal synthesis and pressureless sintering. The amount of fibers was varied from 5 wt % to 15 wt % through hydrothermal synthesis, mullite fibers and hydroxyapatite composite powders were subsequently sintered at temperatures of 1150, 1250, and 1350 °C. The composites presented a more perturbed structure by increasing fiber content. Moreover, the composites experienced pore coalescence and exhibited a dense microstructure at elevated temperature. X-ray diffraction indicated that the composites underwent various chemical reactions and generated silicate glasses. The generation of silicate glasses increased the driving force of particle rearrangement and decreased the number of pores, which promoted densification of the composites. Densification typically leads to increased hardness and bending strength. The study proposes a densification mechanism and opens new insights into the sintering properties of these materials.
