    摘要: A powder composition for producing cordierite is obtained by mixing a water-soluble magnesium salt; a water-soluble aluminum salt; a silicon source selected from the group consisting of organic silicon compounds, silica, silica sol and, silica gel; and an organic solvent, adding to the resultant mixture an ammonia-alkaline solution of ammonium carbonate thereby producing a precipitate, separating the precipitate, and drying the separated precipitate.
