FZR is a blended, refined form of blast furnace slag.
TRADE NAME:
FZR®
DESCRIPTION:
FZR® is a blended, refined form of blast furnace slag which predominantly consists of CaO, SiO2, Al2O3 and MgO. Its mineral composition is a mixture of akermenite (2CaO, MgO, 2SiO2), gehlenite (2CaO, Al2O3 , SiO2) and small amounts of anorthite (CaO, Al2O3, 2SiO2).
FUNCTION:
FZR® is added to a glass batch as a fining agent and its reducing action helps liberate retained gases from the glass batch, which may cause defects such as seeds and blisters. Also, the addition of FZR® forms a lower eutectic with silica resulting in a lower melting temperature and lower energy cost. Furthermore, a more active melt is produced thus improving homogeneity in the batch temperature and composition.
