A method of preparing thermal radiation coating material from waste MgO-Cr2O3 brick

摘要

The present invention mechanically pulverizes the lead with waste magnet; Reacting the waste grinds with an aqueous sulfuric acid solution to prepare a chromite compound having a high Cr ₂ O ₃ content; Provided is a method of preparing a ceramic thermal radiation insulation coating agent having a high thermal radiation rate by mixing the chromate compound, fumed silica and water as a bond dispersant.;Waste macrorefractories, heat radiation. Chrome Ore, Fireproof Paint
