X-ray phase analyze, simultaneous thermal and electron-microscopic analyzes were used to demonstrate the possibility of copper aluminate synthesis with a delafossite structure at a temperature of 1000 °С. It was established that the heating mode significantly affects the phase composition of the final product: with the gradual heating, copper aluminate with a spinel structure is formed, and with the sharp heating, delafossite is formed.
