一种新型保温材料——掺杂改性SiO_2气凝胶

Doped Silica Aerogels——a New High Effective Thermal Insulation

介绍了新型掺杂改性气凝胶的制备工艺以及其导热系数与气压、温度的关系。该材料在高温下具有比普通隔热材料低得多的导热系数,因此用作高效高温隔热材料将颇具前景。

The preparing technique of doped silica aerogels was introduced in this paper. The relationships between its thermal conductivity and air pressure, temperature have been investigated. It is found that the thermal conductivity of silica aerogels doped with titania and inorganic binders is much lower than that of the common insulation. This new high effective thermal insulation has very extensive potential applications.
