Fly ash was pre-treated by magnetic separation and nonmagnetic part of fl y ash (NFA) was used. Maximal crystallization of parent glass occurs in the temperature region from 900 oC to 1160 oC. Glass-ceramics was produced by consolidation of parent glass i.e. pressing (45 MPa) and sintering at 950, 1000, 1050 and 1100 oC, and aluminum silicate (anorthite). The obtained glass-ceramics could be potentially used in construction applications. | URI: | http://hdl.handle.net/20.500.12188/15710 | DOI: | 10.7251/QOL2103085A |
