Abstract
The present invention provides a method of synthesizing amorphous cordierite-forming glasses from organometallic precursors. Either the sol-gel/.beta.-diketonate technique or the amorphous chelating hydroxycarboxylate process can be used advantageously. The method of the present invention can also be used to form 5 component comprised and 2 component comprised amorphous compositions wherein one of the components is an oxide of silicon.
