FIELD: chemistry.
SUBSTANCE: method for obtaining fused-cast potassium fluorophlogopite includes preparation of charge by mixing mica-containing component - vermiculite in quantity 60-90 wt % - and fluorine-containing component - potassium cryolite in quantity 10-40 wt %, melting obtained charge, pouring melt into mould, exposure, extraction of cast from mould and cooling. Preparation of charge is realised by layer-by-layer laying of components, with upper layer of charge consisting of mixture of components. Pouring of melt is realised into preliminarily heated mould.
EFFECT: increase of chemical purity of fluorophlogopite, corrosion and erosive stability of material.
