METHOD OF ENCAPSULATING SPHEROIDS CONTAINING NUCLEAR WASTE

摘要

Method of encapsulating spheroids containing nuclear waste. The spheroids (8) are coated with a composition of from 30 to 85 percent by weight, calculated as SiO2, of a partially hydrolyzed silicon alkoxide (10) and up to 30 percent by weight calculated as Al2O3 of a partially hydrolyzed aluminum alkoxide. The coating on each spheroid is then individually hardened, and is cured by heating to about 500 DEG C to produce a hardened amorphous coating on the spheroids.
