We describe a practical method of synthesis of fluorphlogopite single crystals suited to common laboratoryconditions. The l-atm batch melting technique was adapted using starting compositions having a slight excessof fluorine, added as K2SiF6. The oxide-fluoride mixture was melted above the liquidus temperature and thencooled at a rate of a few degrees per hour between 1400 and 13OO°C. Large (millimetre- to centimetre-size), clearand detachable single crystals were obtained by adding a quench of the charge during the cooling stage. XRD,TEM and electron microprobe analyses confirm that the micas produced are mostly monoclinic IM polytypeshaving chemical compositions very close to the end-member fluorphlogopite. Heating experiments confirm thatmelting of fluorphlogopite is congruent. From both heating experiments and thermal analysis, the melting temperatureof fluorphlogopite is located at values ⩾ 1390°C. Synthetic fluor-mica single crystals are of practical interestas analytical standards, and for several applications in experimental petrology.
