The design of an X‐ray powder diffraction probe and its integration with a multi‐channel reactor system for potential application in high‐throughput experimentation is presented. The working principle of the apparatus is exemplified by measurements of corundum and of the phase change observed when oxidizing vanadium(III) oxide (V 2 O 3 ) in air during heating up to 450 °C. The phase transformations of the parent material were monitored by phase identification of the crystalline intermediate vanadium(IV) oxide (VO 2 ) and the final product vanadium(V) oxide (V 2 O 5 ).
