METHOD FOR PRODUCING MELT-CAST POTASSIUM FLUORINEPHLOGOPITE
?The invention relates to the preparation of synthetic melted mica materials, and specifically relates to a stone casting process and to the composition of an initial feedstock, and may be used in the creation of novel types of stone casting in the metallurgical, mining/enrichment, refractory and construction industries. A method for producing melt-cast potassium fluorine-phlogopite includes preparing feedstock by mixing mica-containing and fluorine-containing components, melting the produced feedstock, pouring the melt into a mold, allowing to sit, removing the casting from the mold, and cooling; according to the claimed invention, the mica-containing component consists of vermiculite (60-90 mass%), and the fluorine-containing component consists of potassium cryolite (10-40 mass%); wherein, the feedstock is melted via the sequential stepped heating thereof, and the feedstock is prepared by layering components, wherein the top layer of the feedstock consists of a mixture of components, and the melt is poured into a preheated mold. The use of the present invention allows for enhancing the chemical purity of the potassium fluorine-phlogopite, increasing the corrosion and erosion resistance of the material, and improving the accuracy of the chemical composition of the yielded product.
