摘要

本研究采用三维(3D)打印技术制备了zr修饰的Si-O-C前驱体陶瓷。通过打印四种不同乙酰丙酮锆含量的前驱体来完成陶瓷烧结。对陶瓷屈服、尺寸收缩率、力学性能和显微组织进行了对比分析。结果表明,随着乙酰丙酮锆含量的增加,4种样品的陶瓷收率和尺寸收缩率均有所提高。含有30 wt%乙酰丙酮锆的样品具有良好的抗压性能,抗压强度为50.2±0.6 MPa。含有40 wt%乙酰丙酮锆的样品表面出现裂纹,而含有10、20和30 wt%乙酰丙酮锆的样品表面相对完整。因此,获得了一种稳定的Si-Zr-O-C前驱体陶瓷,具有良好的力学性能,可用于3D打印。

Preparation and property characterization of Zr-modified Si-O-C-based precursor ceramics through three-dimensional printing

In this study, Zr-modified Si-O-C precursor ceramics were prepared using three-dimensional (3D) printing. Ceramic sintering was completed by printing four precursors containing different zirconium acetylacetone contents. Comparative analysis was conducted on the ceramic yield, size shrinkage, mechanical properties, and microstructure. The results showed that the ceramic yield and size shrinkage of the four samples were increased with the increasing zirconium acetylacetone contents. The sample containing 30 wt% zirconium acetylacetone exhibited good compressive performance, with a compressive strength of 50.2 ± 0.6 MPa. Cracks were observed on the surface of samples containing 40 wt% zirconium acetylacetone, while those containing 10, 20, and 30 wt% zirconium acetylacetone were relatively intact. Therefore, a stable Si-Zr-O-C precursor ceramic with good mechanical properties, which can be used for 3D printing, was obtained.
