In this paper, ZrV2O7 with negative-thermal-expansion(NTE) was prepared and studied by two different synthetic routes-directly-calcined synthesis from oxides and calcined synthesis with the precursor prepared by wet-chemical technique.

• 采用两种不同的制备工艺技术-氧化物直接煅烧反应合成技术与湿化学法制备前驱体一煅烧合成技术,研究了具有负膨胀特性的钒酸锆(ZrV2O7) 材料的制备原理及机制。
