ABSTRACT:
A ceramic nanocomposite made from silicon, oxygen and nitrogen is provided hich has a very low dielectric constant, low dielectric loss along with good strength and hardness. The ceramic nanocomposite finds use in millimeter-wave radomes and microwave radomes used on aircraft which must resist erosion from high speed impact with water, ice and dust in the atmosphere.
