Evacuated insulation panels filled with pyrogenic silica powders: properties and applications
Abstract
The thermal conductivity of pyrogenic silica pcwder boards mixed with a silicon carbide opacifier is measured as a function of gas pressure and of temperature. At room temperature and gas pressures around 1 to 5 mbar the thermal conductivity is about 0.004 W m -1 K -1 . At a mean temperature of 300 C the evacuated panel has a thermal conductivity well below 0.010 W m -1 K -1 , because of the silicon carbide opacifier. Several square metres of vacuum panels have been encapsulated in laminated aluminium envelopes and tested as thermal insulations for building facades.

The diffusion approximation approach is easy to use and has been widely used to calculate the radiative thermal conductivity of insulation materials such as open- and closed-cell foams, silica aerogel powders, and glass fibers.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
