Plasma jets are widely used as a heat source which can cover the temperature range from 3000K to 20000K. Our original new type of plasma jet is operated by gases produced by sublimation of solids. The solids are so placed that the main arc discharges induce the sublimation of solids as well as the augmentation of plasma flames, that is, the gas is generated on demand and no additional electrodes for sublimation of solids are necessary. Experimental results showed that ignitions and extinctions are repeatedly possible, and instantaneous with the application or interruption of arc discharge, employing teflon as the solid, and that sublimation rates of solids are controllable by the power supplied. The efficiency of this type of plasma jet was comparable with that of usual gas plasma jet and was still improved by employing composite type of solids or consumption type of electrodes of which evaporation gases react and evolve chemical reaction energy.

等离子体射流作为热源被广泛应用，其温度范围可以从3000 K到20000 K。我们最初的新型等离子体射流是由固体升华产生的气体操作的。固体被放置成使得主电弧放电引起固体的升华以及等离子体火焰的增强，也就是说，气体按需产生，并且不需要用于固体升华的附加电极。实验结果表明，点火和升华是重复可能的，和瞬时的应用或中断的电弧放电，采用碲作为固体，和固体的升华速率是可控的电源。这种类型的等离子体射流的效率与普通气体等离子体射流的效率相当，并且通过采用复合型固体或消耗型电极，蒸发气体发生反应并释放化学反应能，仍然可以提高效率。
