电热原子化过程中金属氧化物的热分解与还原

本文根据效力学原理，研究了２４种金属氧化物通过热分解和用碳还原产生液、固态或气态金属实现原子化的可能性。计算表明，大多数金属氧化物均可能经过热分解或用碳还原产生液、固态或气态金属，接着液、固态金属原子化成气态．仅有几种金属氧化物不能够通过热分解和用碳还原直接原子化成气态金属。

Thermodecomposition and Reduction of Metal Oxides During the Process of Electrothermal Atomization

According to thermodynamic principles the possibility of realizing atomization for liquidus, solidus, or gaseous metals, produced by thermodecomposing and reducing with carbon 24 kinds of metal oxides, has ben investigated. Thermodynamic calculations show that foe majority of these metal oxides can be thermodecomposed or reduced with carbon to produce liquidus, solidus or gaseous metals, among which the solids and liquids can be subsequently converted to gaseous state by atomization. Only a few metal oxides can not be thermodecomposed and reduced with carbon to directly generate atomized gaseous metals.
