摘要： The invention relates to the geopolymer suspension for insoluble heat- and corrosion-resistant coatings for the surfaces of Fe alloy products that contains 20 to 25% wt. of the aqueous solution of 80% to 90% wt. phosphoric acid, 25 to 30% wt. of aluminosilicate, 4.6 to 5.2% wt. of graphite, and the remainder is isopropyl alcohol. It further relates to the method of preparing the geopolymer suspension, wherein 20 to 25% wt. of the aqueous solution of 80 to 90% phosphoric acid is added to 100 ml of isopropyl alcohol and 25 to 30 g of kaolin is gradually added while stirring at laboratory temperature for 8 to 15 minutes. After 9 to 15 minutes, 4.6 to 5.2 g of graphite as an additive is added at once, and the resulting mixture is homogenised for another 18 to 25 minutes.
