制备SrZrO3的方法以及SrZrO3陶瓷
本发明提供一种制备SrZrO3的方法，制备方法包括将SrCO3和ZrO2混合，压制成坯后置于微波环境中进行处理，处理包括粉体处理或块体处理，粉体处理为加热至1100‑1400℃，保温不少于30min，得SrZrO3粉体；块体处理为加入粉体埋烧，以5‑25℃/min的速率升温至1200‑1650℃烧结，保温不少于30min，得SrZrO3块体。本发明制备的SrZrO3块体具有良好的化学稳定性、机械强度以及高温抗烧结等优良特点，使其可作为低发射率、低热导率、高膨胀系数、耐高温的飞机坦克等军事武器的红外隐身蒙皮材料。同时，本申请还提供一种由上述方法制备的SrZrO3陶瓷。
The invention provides an SrZrO3 preparation method. The preparation method comprises the steps that SrCO3 and ZrO2 are mixed and pressed into a blank, then the blank is placed in a microwave environment to be treated, and the treatment comprises powder treatment or block treatment, wherein the powder treatment comprises the steps: heating the blank to 1100-1400 DEG C, carrying out heat preservation for not less than 30 min, and thus obtaining SrZrO3 powder; and the block treatment comprises the steps: adding powder, burying and sintering, heating to 1200-1650 DEG C at the rate of 5-25 DEG C/min, sintering, and carrying out heat preservation for not less than 30 min to obtain an SrZrO3 block. The prepared SrZrO3 block has the excellent characteristics of good chemical stability, mechanicalstrength, high-temperature sintering resistance and the like, and can be used as an infrared stealth skin material for military weapons such as aircraft, tanks and the like with low emissivity, low thermal conductivity, high expansion coefficient and high temperature resistance. Meanwhile, the invention also provides the SrZrO3 ceramic prepared by the method.
