摘要
本研究以天然铝矾土、工业钛白粉为主要原料，加入少量添加剂，采用一步烧结法研制成功了稳定的钛酸铝、莫来石为主晶相的陶瓷材料。其常温抗折强度为20．0～55．0MPa，热膨胀系数为0．5～3．0×10－6／℃（1000℃），耐火度大于1750℃。
By adopting natural bauxite and industrial titanium dioxide as main raw materialsand adding a few additives into the composition, a stable ceramic material with aluminium titanate and mullite as key crystalline phase is sucessfully developed through single sinteringwhich has the bending strength 20. 0~55.0MPa at room temperture, thermal expansion coefficient 0. 5~3.0× 10-6/℃ (1000℃) and refractoriness 1750℃.
