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.
