Patent  195293
 A transparent amorphous AlO(OH).aH2O glass having transparency from 75 to 95%, preferable 85 to 95% with or without doping with rare-earth or other metal cations and a process of preparing the same. The transparent amorphous AlO(OH).aH2O glass having purity of 99.5 to 99.9%, preferably 99.9%. the process involves providing surface treated Al-metal having highly reactive nascent Al; hydrolysis of the surface treated Al-metal to provide AlO(OH).aH2O in gel form; heating in the temperature range of 75 to 950 C, preferably 80 to 900 C to a homogenous viscous mass followed by quenching.
