COMPOSITE COMPOSITION COMPOSED OF OXIDES AND A MANUFACTURING METHOD OF STRENGTH IMPROVED CERAMICS USING THE COMPOSITE COMPOSITION CAPABLE OF ENHANCING THE STRENGTH OF CERAMICS

摘要

PURPOSE: A composite composition composed of oxides and a manufacturing method of strength improved ceramics using the composite composition are provided to improve strength by spreading the ceramic surface with the composite composition, mixing with ceramic materials, and sintering at a predetermined temperature.;CONSTITUTION: A composite composition composed of oxides comprises 35-45 wt% of silicon dioxide (SiO2), 25-35 wt% of alumina (Al2O3), 0.1-7 wt% of iron trioxide (Fe2O3), 0.1-1.3 wt% of calcium oxide (CaO), 2.38-9.38 wt% of potassium oxide (K2O), 0.1-3.9 wt% of magnesium oxide (MgO), 0.1-2.8 wt% of sodium oxide (Na2O), 0.01-1.83 wt% of phosphorus pentoxide (P2O5), 1-5 wt% of titanium dioxide (TiO2) and 0.01-1.83 wt% of manganese oxide (MnO). The composite composition additionally includes 13-81 wt% of alumina based on the total wt% of silicon dioxide. The composite composition is pulverized into powder greater than 81mesh. The composite composition and water are mixed at a mass ratio of 1-2:1.;COPYRIGHT KIPO 2013
