Mn₃Al₂Si₃O₁₂ crystals were grown experimentally at atmospheric pressure and at temperatures 1235°C from a molten stoichiometric mixture of tephroite (Mn₂SiO₄), γ -alumina (Al₂0₃) and quartz (SiO₂) Their habit is identical to that of natural grown Mn₃Al₂Si₃O₁₂ crystals. Using AFM (Atomic Force Mycroscopy) technique are shown the steps of growing crystals.
