Physico-technological institute of Metals and Alloys of National Academy of Sciences of Ukraine (Kyiv, Ukraine)* Ltd «Zaporozhye titanium-magnesium plant» (Zaporizhzhia, Ukraine) Received 11.11.2021 UDK 621.74:666.85/86.061.62 Periodic production of stone-cast products by metallurgical enterprises for their own usage is associated with solving the problems of non-serial production. First of all, these are the risks of inconsistency of charge materials, since the initial oxide charge materials (quartz sand, chamotte powder, periclase) are not subject of sufficient input control for chemical and mineral compositions, and the usage of chemically pure oxides as charge materials for stone casting materials in production - economically impractical. It was shown that usage of cast structure modifiers (SiC, B4C, ZrSiO4) for fluorophlogopite casting, compensates the insufficient input control of mineral composition of the charge, and provides effective decreasing of the cast mica crystals size even in large size casting.   References 1 Aidenzon M.
