A novel polymer precursor method for the preparation of silicates including enstatite‐free forsterite is being investigated. Precursors to crystalline materials were prepared via the copolymerization of the K and/or Mg salts of methacrylic acid with various combinations of a siloxane‐methacrylate and a methoxysilyl‐methacrylate Thermogravimetric/differential thermal, pyrolysis mass spectrometry, and high‐temperature X‐ray diffraction analyses were used to monitor the conversion of the precursors to inorganic oxide during air pyrolysis. Some precursors to crystalline oxides showed yields as high as 77% of theoretical.
