Abstract
A method for the production of refractory products, non-reactive with molten aluminum, other molten metals and with molten alloys is provided. A formed refractory product is made non-reactive to molten metals/alloys by impregnating the product with a solution containing fluosilicic acid, fluoroboric acid, hydrogen fluoride and mixtures thereof, and subsequent heating of the impregnated product to cause the formation of non-reactive surface.
