Fabrication of adiabatic foam by sodium silicate with glass fiber as supporting body

Fabrication of adiabatic foam by sodium silicate with glass fiber as supporting body was researched in this paper. The variation of the thermal conductivity, density, and compression strength with the sintering temperature, modulus of sodium silicate and glass fiber content were characterized. The results show that through sintering at 450 °C with 3.3 modulus of sodium silicate and less than 0.67 wt.% content of glass fiber, the adiabatic foam with 0.0454-0.0459 W/m K of thermal conductivity, 74-80 kg/m3 of density, and 0.42-0.46 MPa of compression strength can be obtained. Therefore, this adiabatic foam has a large potential of thermal insulation application.
