High-temperature-resistant porous interlayer wave-transmitting material and preparation method thereof
The invention relates to a high-temperature-resistant porous interlayer wave-transmitting material and a preparation method thereof. The wave-transmitting material comprises a core layer and a skin for enabling the core layer to be clamped in the middle. The raw materials for preparing the core layer and the skin comprise silicon and silicon nitride, or mixture powders of the silicon and the silicon nitride; the finally-prepared skin and the core layer are made of silicon nitride; and porosity of the core layer is 70-92%, and porosity of the skin is 20-56%.
