Abstract
Chemically ultra-homogeneous gels have been prepared, in the SiO2-Al2O3 system, using new metal-organic precursors with Al-O-Si linkages. By thermal treatment at 900°C, transparent monolithic gels lead to aluminosilicate glasses and above 1000°C, to optically transparent glass-ceramics (for instance by homogeneous crystallization of mullite in an amorphous silica matrix).
