摘　　要：以天然透锂长石、高岭土、滑石、紫木节为原料,采用正交试验方法制备了透锂长石/堇青石低膨胀复合陶瓷材料。研究结果表明,在1280℃烧成温度下,保温30 min时,可以制备出性能优异的复合低膨胀陶瓷材料,其烧成收缩率、吸水率、热膨胀系数和抗折强度分别为9.80%、0.03%、0.99×10-6/℃、64.09 MPa。The low expansion petalite-cordierite ceramic complex material was prepared with natural mineral petalite, kaolin, talc, Zimujie as raw materials by orthogonal test method. Results showed that when sintered at 1280 ℃ for 30 min soaking period, the low expansion ceramic complex ceramic material with excellent properties could be prepared. The shrinkage, water absorption, coefficient of thermal expansion and flexural strength of the optimal ceramic complex materials was 9.80%, 0.03%, 0.99×10-6/℃, 64.09 MPa respectively.
