Latest Patents

Christian Richard's latest patents include a method for producing a sheet of paper comprising calcite. This invention involves a unique process where an aqueous composition containing calcium bicarbonates and/or carbon dioxide is mixed with calcium hydroxide. This mixture precipitates calcium carbonate in the form of vaterite crystals, which are then transformed into calcite crystals upon contact with paper fibers. The resulting mixture is processed through a papermaking machine to form a sheet of paper.

Another significant patent by Richard is a method for fixing a mineral filler on cellulosic fibers. This method utilizes an aqueous cellulose-fiber suspension derived from papermaking, which includes hydrogen carbonates, carbonates, or silicates. By adding a hydroxide of the filler mineral to this suspension, the carbonates or silicates are precipitated onto the fibers, enhancing the quality of the paper produced.
