In the production of nitric acid, the concentrated nitric acid has strong corrosion performance at high temperature, so it is crucial to select suitable material to manufacture the equipment. Contrasts the corrosion rates in nitric acid of niobium, tantalum, tantalum -2.5 tungsten alloy, aluminum, high silicon cast iron, polytetrafluoroethylene (PTFE) and other materials, the results show that niobium has a low corrosion rate in high-temperature concentrated nitric acid, and its economic benefit is remarkable.
