【Abstract】 In this paper, the condition of zircon decomposition in the presence of sodium fluosilicate is studied by DTA. The result shows that a endothermic peak exists apparently in DTA curve of zircon decomposi- tion, and the suitable decomposition temperature should be controlled at 563 to 588℃. The effect of addition on decomposition temperature is minor. The proportion of the raw materials has a certain effect, and particle size has a remarkable influence.更多还原
