【Abstract】 Systematic investigation was made so as to allow practical USC of aluminum titanate. Its two fatal drawbacks were overcome by the following comprehensive ways: surplus Al2 03 in the formulation, addition of mullite (or formation of mullite at high tem- perature) to suppress the thermal decomposition of aluminum titanate, and optimal introduction of MgO and Cr2O3 . The batch of aluminum titanate mainly consists of natural raw materials,so its product with low cost and higher performance can be practical- ly used.更多还原
