Antioxidant high-temperature wave-absorbing material and preparation method thereof
The invention provides an antioxidant high-temperature wave-absorbing material and a preparation method thereof. The problems that an existing wave-absorbing material is poor in oxidation resistance at the high temperature and poor in electromagnetic wave absorption performance at the high temperature, and a high-temperature wave-absorbing material is high in preparation cost, complex in preparation process, low in yield, large in density and the like are solved. The material has the molecular formula of LaxSr2-xMgMoO6-delta, x is 0-0.1, after heat preservation is conducted for 2 h at the temperature of 800 DEG C, the phase is still not decomposed, and the material has good oxidation resistance and good impedance matching and attenuation characteristics (namely the electromagnetic wave absorption characteristic) at the high temperature, can be prepared in a large scale and is an anti-oxidation high-temperature electromagnetic wave absorption material from the room temperature to the temperature of 800 DEG C.
本发明提供了一种抗氧化高温吸波材料及其制备方法,解决了现有吸波材料存在高温下抗氧化性能差,高温下电磁波吸收性能欠佳以及高温吸波材料制备成本高,制备工艺复杂,产量低、密度大等问题。分子式为LaxSr2‑xMgMoO6‑δ,其中,x的取值是0‑0.1的材料,在800℃,保温2h后,物相仍然没有分解,具有很好抗氧化性,在高温下具有好的阻抗匹配和衰减特性(即电磁波吸收特性),可大量制备,是一种从室温到800℃抗氧化高温电磁波吸收材料。
