【Abstract】 Mixed ash samples were prepared by adding coal ashes and additives of K 2O and Na 2O in different ratios. The melting characteristics and the mineral composition of the samples were investigated and a ternary phase diagram was used. Under the condition of reducing atmosphere, it is shown that the melting point characteristics of the samples were similar to those of the phase diagrams of the ternary systems K 2O Al 2O 3 SiO 2 and Na 2O Al 2O 3 SiO 2. At high temperature, the mineral composition of the samples was nearly as same as that of the ternary systems.更多还原
