论文摘要
以2.45 GHz的频率研究了3Y-ZRO 2的直接微波加热。测试了输入功率，样本位置和大小的不同条件。首次解释了有效培养基近似和有限元方法的微波烧结的实验已知的不稳定性。我们展示了随着温度和相对密度增加的材料介电介电常数假想部分，从而促进了高热点现象。结果表明，样本位置对
Direct microwave heating of 3Y-ZrO 2 is studied at frequency of 2.45 GHz. Different conditions of input power, sample position and size are tested. For the first time, the experimentally known instability of microwave sintering is explained coupling the effective medium approximation and finite-element method. We show how the material dielectric permittivity imaginary part which increases with temperature and relative density encourages high hot spot phenomena. It is shown that the sample location has a great impact on the
