ABSTRACT:
Phosphate ceramic backing blocks are provided for the profile sanding of wood. The blocks are made of rigid, non-foamed phosphate ceramic. The ceramic is dimensionally stable in spite of friction-caused heat, and also has a semi-polished finish that is achieved without polishing. The phosphate ceramic block is simply made by molding the wet reaction mixture for the ceramic, and then curing the ceramic mixture.
