This paper presents a further analysis of important SPS parameters which leads to control the interaction plasma jet-suspension. A particular attention is paid to the treatment of liquid materials mechanically injected (suspension jet or drops) according to different working parameters such as the plasma mixture and the injection pressure. Concerning the suspension injection, by observing the suspension drops injection with a fast shutter camera triggered by a defined voltage level of the plasma torch, it is shown that plasma jet fluctuations have a strong influence on drops fragmentation. %8 2006-12-01
