Synthesis of preceramic organomagnesiumoxanealumoxanes

Preceramic organomagnesiumoxanealumoxanes hydrolytically stable in air and soluble in organic solvents, exhibiting fiber-forming properties at Al: Mg molar ratios of 2: 1 and 1: 1, have been synthesized for the first time. The physicochemical properties of the organomagnesiumoxanealumoxanes and ceramic samples prepared from them have been studied by a variety of techniques (nuclear magnetic resonance, IR spectroscopy, scanning electron microscopy, thermogravimetric analysis, X-ray diffraction, and elemental analysis).
