High-temperature-resistant ceramic material based on hafnium boride and preparation method thereof
The invention discloses a hafnium boride-based high-temperature-resistant ceramic material and a preparation method thereof in the field of ceramic materials. The hafnium boride-based high-temperature-resistant ceramic material comprises the following components in parts by weight: 70-90 parts of modified hafnium boride fibers, 4.5-13.5 parts of zirconium carbide, 5-15 parts of silicon powder and 0.5-1.5 parts of carbon powder. According to the invention, the hafnium boride fiber is doped and modified, so that the sintering performance of the ceramic material is improved, and the compactness and high-temperature oxidation resistance of the high-temperature-resistant material are improved.
本发明公开了陶瓷材料领域的一种基于硼化铪的耐高温陶瓷材料及其制备方法，包括如下重量份的组分：改性硼化铪纤维70‑90份、碳化锆4.5‑13.5份、硅粉5‑15份、碳粉0.5‑1.5份。本发明提出通过对硼化铪纤维进行掺杂改性的方式，提高了陶瓷材料的烧结性能，从而提高耐高温材料的致密性和耐高温氧化能力。
