采用砂磨工艺获得了亚微米氧化铝复合粉体，用于制备微晶氧化铝陶瓷基板，研究了浆料组成对浆料流变学性质、生坯密度、生坯应力-应变行为的影响，以及烧结制度对平均晶粒尺寸和基板抗弯强度的影响。结果表明，固相含量、R值(增塑剂和黏结剂的质量比)和分散剂用量等关键因素决定了流延浆料的流变学性质。R值增大导致生坯强度和密度降低，提高固相含量有利于增加最大可流延厚度，优化工艺条件下可制备0.16~1.20 mm的坯片。当烧结温度为1 550 ℃、升温速率为2.5 ℃/min、保温时间为60 min时，制备的陶瓷基板平均晶粒尺寸为1.1 μm左右，晶粒尺寸分布均匀，抗弯强度达到(440±25) MPa。 The submic...
