China has announced the discovery of a new cerium-rich silicate mineral, Nipeiite-(Ce), which has been officially recognized by the International Mineralogical Association. Found in a rare-earth mine in Henan Province, this mineral is named in honor of Professor Ni Pei from Nanjing University for his contributions to the study of tungsten and rare-earth deposits. The mineral, which possesses the highest cerium content to date, is anticipated to have applications in advanced technology sectors, including aerospace, due to its high-temperature and compression resistance properties
The discovery was made through meticulous fieldwork and analysis, identifying unusual elements leading to the confirmation of the new mineral’s unique physical, chemical, and crystal structure. With a density of 4.943 grams per cubic centimeter and colors ranging from light red to reddish-brown and grayish-white, Nipeiite-(Ce) not only contributes to geological knowledge but also holds potential economic value and implications for solid physics and chemistry. This marks the second new mineral discovery by the Tianjin geological survey center’s team in Taiping town, following Taipingite-(Ce), and underscores China’s growing presence in the global mineral research arena. Out of the 6,006 known natural minerals, China has identified 192, representing around 3 percent of the global total.
China has discovered a new silicate mineral, known as Nipeiite-(Ce), with the highest cerium content found so far, in a rare-earth mine in Central China’s Henan Province. The mineral has been recognized by the International Mineralogical Association, China’s Ministry of Natural Resources announced on Friday. An expert noted that it can be used in high-tech areas such as aerospace.
