 inside the shock tube for millisecond (ms) time scale. The objective of the work is to investigate the behavior of SiO<sub>2</sub> powders upon interaction with the high temperature shock-heated nitrogen gas. The SiO<sub>2</sub> samples are characterized using different experimental techniques to understand the effects of shock interaction and to study the non-catalytic behavior of SiO<sub>2</sub> powders as it form new compounds on interaction with test gases at the experimentally simulated high temperature conditions. The high temperature imparted by shock wave is absorbed by SiO<sub>2</sub> and undergoes phase transformation as evident from the XRD patterns. SEM and TEM studies show the formation of spherical particles after shock treatment due to the superheating and cooling of fine powders. XPS studies show the formation of silicon nitride and silicon oxy-nitride resulting from the interaction of high temperature nitrogen gas, confirming the non-catalytic behavior of SiO<sub>2</sub> powders.&picture=http://www.aascit.org/aascit/decorators/img/journal/891.jpg)

Application of shock tubes for the interaction of shock-heated test gases with SiO2 fine powders has been demonstrated for the first time in this work. Fine SiO2 powders are made to interact with shock-heated test gases at reflected shock temperatures of 1960–3990 K (estimated) inside the shock tube for millisecond (ms) time scale. The objective of the work is to investigate the behavior of SiO2 powders upon interaction with the high temperature shock-heated nitrogen gas. The SiO2 samples are characterized using different experimental techniques to understand the effects of shock interaction and to study the non-catalytic behavior of SiO2 powders as it form new compounds on interaction with test gases at the experimentally simulated high temperature conditions. The high temperature imparted by shock wave is absorbed by SiO2 and undergoes phase transformation as evident from the XRD patterns. SEM and TEM studies show the formation of spherical particles after shock treatment due to the superheating and cooling of fine powders. XPS studies show the formation of silicon nitride and silicon oxy-nitride resulting from the interaction of high temperature nitrogen gas, confirming the non-catalytic behavior of SiO2 powders.
