Loehman (1982) have also prepared yttrium sialon glasses which appear to be highly refractory glasses and require high processing temperatures (up to I700 C). 

Rare-earth sialon glasses may also have practical applications, for example as fibers for reinforcement, joining agent for ceramics, protective coatings, nuclear waste materials or as seen before, as neutron-absorbent glasses.
