Full Title

Full titles differ between systems:

IPC:

Silicon; Compounds thereof > Silicates > having base-exchange properties but not having molecular sieve properties > Amorphous silicates, e.g. so-called "amorphous zeolites"

CPC:

Silicon; Compounds thereof ( C01B21/00, C01B23/00 take precedence; persilicates C01B15/14; carbides C01B32/956) > Silicates (persilicates C01B15/14 ) > having base-exchange properties but not having molecular sieve properties (regeneration thereof B01J49/00) > Amorphous silicates, e.g. so-called "amorphous zeolites" (crystalline zeolites C01B39/00)
