稀土颜料来了！色彩鲜艳又环保

Core Viewpoint - The development of a new generation of environmentally friendly pigments by a research team led by Professor Dong Bin addresses the issue of toxic heavy metals in traditional pigments, offering vibrant colors at a lower cost without harmful substances [1][4]. Group 1: Research and Development - The research team, originally focused on rare earth studies, identified the contradiction in the pigment industry where vibrant colors rely on toxic heavy metals [2]. - The team utilized the optical properties of rare earth ions to create a new type of pigment that avoids heavy metal toxicity while achieving high color saturation [2][3]. - Overcoming technical challenges, the team conducted thousands of experiments to optimize the optical behavior of rare earth ions and the saturation of color [3]. Group 2: Cost and Production - The new pigments are based on silicate materials, which are abundant and inexpensive, allowing for a significant reduction in production costs [4]. - The team estimates that the price of the new environmentally friendly pigments can be reduced by over 60% compared to existing high-end alternatives [4]. Group 3: Industry Impact and Future Plans - The introduction of these new pigments is expected to drive a technological transformation in the pigment industry, encouraging more companies to adopt green production methods [5]. - The team has successfully produced stable outputs in green, yellow, orange, and red pigments and plans to establish a 500-ton pilot production line in collaboration with local authorities [5]. - Future applications are being explored in various fields, including construction, ceramics, and automotive coatings, with an aim to cover the entire color spectrum [5].
