Si2N2O high-temperature-resistant wave-transparent ceramic and preparation method thereof
The invention discloses a Si2N2O high-temperature-resistant wave-transparent ceramic and a preparation method thereof. The method comprises the steps: selecting silicon monoxide as a main powder raw material, and carrying out the gel casting to form porous ceramic, so the porosity and the wave-transparent performance of the ceramic are improved on the premise that it is guaranteed that the ceramic material has the excellent mechanical property. The porous Si2N2O ceramic prepared by the invention has excellent corrosion resistance, thermal shock resistance, oxidation resistance, mechanical property and wave-transparent property, and is a high-temperature-resistant wave-transparent material with comprehensive mechanical, thermal and electric properties.
本发明公开了一种Si2N2O耐高温透波陶瓷及其制备方法，选用了一氧化硅为主粉体原料，注凝成型多孔陶瓷，在保证陶瓷材料具有优异力学性能的前提下，提高了陶瓷的气孔率，以及陶瓷的透波性能。本发明制备的多孔Si2N2O陶瓷具有优异的耐腐蚀性、抗热震性、抗氧化性、力学性能和透波性能，是一种具有力、热、电综合性能的耐高温透波材料。
