摘要: The invention concerns a process for the extraction of acid or basic oxides contained in a vegetal matter, more specifically it concerns the extraction of silica from rice husks. The invention also concerns pure oxides extracted from vegetal matter. The invention also concerns the process for the extraction of carbon-rich oxide compositions from vegetal matter, and compositions obtained through said process.
