Material testing is a crucial step during the design process as particular materials serve as safety and life saving conditions. In this study, a MoSi2 is chosen as the target specimen to undergo impact under high temperatures. An impact apparatus is designed and constructed for the purpose of propelling alumina particles at high velocities. A nozzle using compressed nitrogen gas is used to fire the particle at the desired velocities. Due to the possibility of thermal shock occurring at higher temperatures, a separate nozzle utilizing vitiation heating is designed to fire the particle at equally higher temperatures to prove the lack of thermal shock. Throughout the experiment, measurements including particle velocity, exit temperature, specimen temperature, and damage of the specimen are documented in both the cold test nozzle and vitiated heating test nozzle to propose a reliable method in the impact testing of
