Popis:	Using quartz sand (SiO2); Al and Mg powders as reducing agents; a waste product of aluminum production, cryolite Na3AlF6, as a source of fluorine; and commercial KClO4 as a source of oxygen, we made an attempt to synthesize cast fluorophlogopite, NaMg3Si3AlO10F2, by metallothermic SHS in open air. Synthesis conditions have been optimized with respect to preparation of either cast or porous resultant materials. The synthesized materials were found to contain NaMg3AlSi3O10F2, Na4Mg6Al4Si4O20F4, MgAl2O4, SiO2, and some amount of unreacted Si. Our results can be regarded as a technological basis for designing a process for SHS production of fluorophlogopites.
