Yamane and Okano ( 1979 ) suggested that such large pores might be essential
for the conversion of bulk gels to large glass bodies without generating cracks . It
was indicated that higher hydrolysis temperatures such as 70°C favor the ...

tration is important in making bulk glass bodies . The gel was heated slowly ,
especially between room temperature and 250°C , where most of the water and
organic matter leave the gel , and at about 800°C , where water - forming silanol

This is valuable since homogeneous bulk glass which cannot be prepared by
conventional melting techniques because of its tendency to phase separation or
crystallization or because its melting temperature is too high can now be
prepared .
