等离子体目前已在国内外的冶金过程中应用。预计在今后的十年内将会出现年产几万吨到几十万吨铁合金或铁金属的等离子工业装置。等离子体是一种新的能源技术,简单地说是把气体通过电弧而使之电离,这就是等离子体。这时的气体不具有分子结构,而是由带电的正离子和电子组成,例如O_2→2O~(2+)+4e。显然等离子体在总体上说是电性中和的。所以有人把它叫做物质的第四态,因而 Plasma is currently used in metallurgical processes at home and abroad. It is estimated that there will be plasma industrial installations with an annual capacity of tens of thousands tons to several hundred thousand tons of ferroalloy or ferrous metal within the next ten years. Plasma is a new energy technology, simply put the gas through the arc and ionization, which is the plasma. The gas at this time does not have a molecular structure, but consists of charged positive ions and electrons, such as O 2 → 2O ~ (2 +) + 4e. Obviously the plasma is electrically neutral as a whole. So some people call it the fourth state of matter, thus
