UVC-LED支架氮化铝(AlN)和氧化铝(Al2O3)陶瓷材料性能对比表

发表时间:2020-08-24 12:51

氮化铝(AlN)和氧化铝(Al2O3)是UVC-LED常用的支架材料,除了材料不同外,制备工艺的区别也会导致其外观、颜色、导热系数有比较大的差异。详细对比可见下图。需要注意的是,AlN陶瓷为黑色,氧化铝陶瓷有白色、灰色、黑色三种。

Aluminum nitride (AlN) and alumina (Al2O3) are commonly used as support materials for uvc-led. In addition to different materials, the differences in preparation process will also lead to great differences in appearance, color and thermal conductivity. The detailed comparison is shown in the figure below. It should be noted that AlN Ceramics are black and alumina ceramics are white, gray and black.
