Trimetallic double alkoxide precursor

Synthesis and Characterization of a Trimetallic Double-Alkoxide Precursor to Potassium Aluminosilicate... 

A novel, soluble trimetallic double alkoxide precursor to potassium aluminosilicate (KAlSi04) has been synthesized by a one pot procedure and its structure characterized. The process termed the oxide one pot synthesis (OOPS) process uses simple, inexpensive chemicals, silica and aluminum hydroxide, to form a processable precursor in one simple step. The precursor is relatively stable to moisture and can be handled in air for long periods of time with minimal hydrolysis. On pyrolysis in air, to 1100" C, it produces phase-pure KAlSi04. The proposed precursor was characterized using thermogravimetric analysis, multinuclearNMR, and mass spectroscopy. The results suggest the precursor disproportionates in solution.
