Physico-Chemical Features of the Synthesis of Mullite in Mixtures of Quartz-Pyrophyllite Rock with a Fluoride-Forming Component

It is established that the use of an ammonium fluoride treatment on quartz-pyrophyllite rock (45% pyrophyllite and 53% quartz) at 650°C changes the traditional mechanism by which mullite is synthesized; it is formed not from metapyrophyllite but from fluoridated pyrophyllite, with the formation of a...
