The situations of foreign large scale concentrated nitric acid production technology, equipment and material selection are introduced,issues,such as production method,production scale, scientific experiment and technical and economic index,etc.of large scale production process of concentrated nitric acid in China are analyzed.To realize large scale production of concentrated nitric acid in China,in the respect of equipment material selection,the original high silicon cast iron should be abandoned,and the materials which can resist the corrode of both concentrated nitric acid and dilute nitric acid should be selected and used.
