Abstract

Abstract:

Through the patent analysis of key technologies such as salt lake magnesium extraction technology and magnesium alloy,the technological advantage countries in different links of global magnesium industry chain were obtained. In terms of the patentee ranking of magnesium alloy,companies in Japan and South Korea show advantages.Based on the analysis of the patentee,the main research teams in the field of magnesium technology and other important information in China were mined.By analyzing the patent layout of magnesium industry in China and Qinghai province of China,the technological advantages of the provinces of China′s magnesium industry and relevant research and development institutions were determined.The current level and possible breakthrough points of Qinghai province in the field of magnesium industry were summarized.The key technologies of magnesium industry were navigated and explored,and the research value and development space of magnesium industry were deeply analyzed.At the same time,the advantages and disadvantages of the industrial development of salt lake in Qinghai were analyzed.Based on the full text,it was proposed that the future development of Qinghai magnesium industry should combine with local characteristics to increase the number of patent applications,comprehensively develop and utilize resources,improve key technologies,strengthen the introduction of talents,and promote the deep integration of industry,universities and research institutes.

Key words: salt lake, magnesium industry, magnesium extraction, patent navigation
