AI Technical Summary
The existing silicon oxide and alumina aerogel composite materials cannot meet the requirements of large-size complex components that are resistant to high temperature, low thermal conductivity, and high strength in aerospace, nuclear power, high temperature industrial furnaces and other fields.
The lanthanum zirconate doped aerogel composite material is prepared by zirconate-lanthanum sol preparation, lanthanum zirconate aerogel modified fiber, porous prefabricated body preparation, sol impregnation and aging, supercritical drying, and high-temperature sintering processes.
It realizes the high temperature resistance, low thermal conductivity and high strength characteristics of lanthanum zirconate doped aerogel composite material, with a maximum size of up to 1500mm×800mm×100mm, and is suitable for high temperature thermal insulation materials.
