    Abstract:

    Al2O3 doped SiO2 nanoporous transparent-wave/ heat-insulation materials were prepared by sol-gel
    method. The effects of Al2O3 to the thermal stability, dielectric and insulation properties were investigated. It was
    showed that the thermal stability enhanced by the doping of Al2O3, which hindered the sintering of SiO2 particles. The
    dielectric constant fits the Lichtenecker's equation. The influence of Al2O3 to the insulating properties was eliminated
    maximatily by multi-layer structure.
