| 摘 要： | 研究了退火时间和碳对低温烧结AlN陶瓷的介电性能,特别是介电常数的影响.结果表明,退火时间通过改变氧在AlN晶格中的扩散过程对介电常数产生极大的影响.随着碳含量的增加介电常数迅速增大,但对介电损耗的几乎不产生影响.

| Abstract: | The article studies the dielectric property of annealing time and carbon for sintering AIN ceramics at low-temperature,espcially,the effect of dielectric constant. The result shows that annealing time importantly influenced dielectric constant through the alteration of oxygen inpurities in AlN lattice.Dielectric constant changes greatly with additives of nano carbon,but almost no effect on dielectric loss. |
