Abstract (en)
The invention relates to honeycomb structures based on lignocellulosic materials and processes for producing these structures. In accordance with the invention there is provided a lignocellulosic structure comprising a thin layer comprising SiO 2 on at least part of its surface. A process of the invention involves contacting a lignocellulosic material, preferably in a continuous fashion, with a SiO 2 precursor.
