25 November 1992 Improved monolithic aerogel for transparent glass spacer in innovative windows

A collaborative research program is engaged to produce `super window' elements with monolithic silica aerogel used as a spacer between two glass panes. The first improvement is a new precursor called polyethoxysiloxane, for an easier and shorter process. This modification is followed by optical measurements, introducing a new concept: the `transparency ratio.' And we show how the diffuse part of the transmitted light may be corrected by the chemical composition and process. With the two further improvements (`in situ' production of aerogel and CO2 substitution method) we anticipate progress toward a high transparency of the final product.
