The new technology opens up new ways for the preparation of high-purity rare earth metal ytterbium targets

With the rise of high-tech industries, high-purity rare earth metals and alloy targets have been continuously applied in new energy vehicles, integrated circuits, new displays, 5G communications and other fields due to their good physical and chemical properties, and have become indispensable key materials for the development of high-tech industries.
Rare earth targets, also known as coating targets, can be simply understood as the use of electrons or high-energy lasers to bombard the target, and the surface components are sputtered out in the form of atomic groups or ions, and finally deposited on the surface of the substrate, undergo the film-forming process, and finally form a thin film. High-purity rare earth metal ytterbium target belongs to high-purity rare earth metal and alloy target, is a high-end rare earth application product at the international advanced level, mainly used for new organic light-emitting material (OLED) display materials, such as Apple, Samsung, Huawei and other brands of mobile phone displays, smart TVs and various wearable devices.
At present, Baotou Rare Earth Research Institute has built an international leading production line of high-purity metal ytterbium target products for OLED, with a production capacity of about 10 tons/year, breaking through the low-cost, high-efficiency and high-quality preparation process technology of high-purity metal ytterbium evaporation materials.
The success of the research and development of “key technologies for the preparation of high-purity rare earth metal ytterbium and target materials by vacuum distillation” of Baotou Rare Earth Research Institute marks the successful localization of rare earth targets, which means that China’s international status in the direction of high-purity rare earth metal materials has been improved, and high-performance electronic devices can also get rid of dependence on the United States, Japan, South Korea and other countries, with significant economic and social benefits.
In addition, through the specification of the manufacture and application of high-purity metal ytterbium targets, he presided over the formulation of the “Ytterbium Metal Targets” group standard. Promote the technological upgrading of upstream production enterprises, help the rapid development of downstream panel manufacturers, take the road of high-purity metal ytterbium target technology research and development, standard formulation, marketing and industrialization, and achieve the high-quality development of high-end rare earth manufacturing industry.
Since the transformation of project achievements, the compound annual sales volume of target products has increased by about 10%, and in the past three years, the annual sales have been more than 10 million yuan, and the output value has reached nearly 50 million RMB.
