Abstract A zirconium (IV) oxide powder was successfully synthesized from the detonation of an explosive emulsion previously mixed with zirconium sulfate tetrahydrate salt (Zr(SO4)2·4H2O) as a ceramic precursor. After detonation of the energetic mixture in a detonation tank, the as-synthesized ceramic material was purified and characterized by X-ray diffraction, transmission and scanning electron microscopy techniques, nitrogen physisorption and dynamic light scattering. The ceramic powder is made of crystalline nanosized particles exhibiting a homogeneous sphere-like morphology. An attempt to explain the oxide ceramic synthetic mechanism is discussed. The detonation synthetic route implementing high temperatures and high pressures in a short time may be seen as an encouraging method for large-scale production of nanopowder.

硝酸铵基炸药乳液爆轰合成ZrO2

摘要 以四水硫酸锆盐(Zr(SO4)2·4H2O)为陶瓷前驱体，通过爆炸乳液的爆炸成功合成了氧化锆(IV)粉末。高能混合物在爆震罐中爆炸后，合成的陶瓷材料被纯化，并通过 X 射线衍射、透射和扫描电子显微镜技术、氮物理吸附和动态光散射进行表征。陶瓷粉末由具有均匀球形形态的结晶纳米颗粒制成。试图解释氧化物陶瓷的合成机理。在短时间内实现高温高压的爆轰合成路线可能被视为纳米粉体大规模生产的一种令人鼓舞的方法。
