铝掺杂超细氧化锌粉体的制备与性能研究
Preparation and Properties of Aluminum-Doped Zinc Oxide Ultrafine Powders
摘要
Abstract
Aluminum-doped zinc oxide (AZO) ultrafine powders were synthesized by the homogeneous precipitation method with Zn( NO3)2·6H2O 和 Al( NO3) 3 ·9H2O as raw materials, and the AZO ultrafine powders were characterized by XRD, SEM, nanoparticle size analyzer and Four-point probe, resistivity. The effects of reaction temperature, calcination temperature, reactant concentration, aluminum dopant content and dispersant content on shape, size and resistivity of the AZO ultrafine powders were examined in detail. The experimental results show that the ZAO powders have the wurtzite structure; the formation of ZAO crystal phase is good at the calcination temperature 550 ℃ ; With increasing the aluminum dopant content, the resistivity of the ZAO powders decreases, and the lattice parameters decrease, however, when the dopant content exceeds 2.0 mol% , the spinel phase is produced, and the resistivity begins to increase.关键词
