In recent days, several production lines of BTXT Rare Earth Material Technology Research Group have been fully started and orderly production has taken place.
A new batch of ordered products for high-purity rare earth metal ytterbium targets are being produced in an orderly manner.
High purity rare earth metal ytterbium target preparation technology is applied to the metal cathode layer of OLED displays. Rare earth metal ytterbium is used to replace metal magnesium and silver cathodes, and is applied to OLED displays, including mobile phones and new digital watches. When used, it has the characteristics of low energy consumption, high resolution, and high color saturation. Without increasing battery energy consumption, it can enhance the durability of electronic products such as mobile phones.
"Due to the immature production technology, in the past, most of China's high-purity rare earth metal ytterbium targets were imported from abroad, which was extremely detrimental to the production of domestic electronic equipment, not only increasing production costs, but also restricting the supply of targets.".
The company's research and development team has developed a high-purity rare earth metal ytterbium target and profile preparation technology with independent intellectual property rights through systematic research on the preparation process technology of high-purity metal ytterbium targets, achieving the goal of accurately controlling the composition and microstructure of alloy targets.
The preparation technology of high purity rare earth metal ytterbium target for BTXT consists of various processes, among which the quality of the distillation process is directly related to the yield and quality of ytterbium metal.
The company's pioneering high vacuum and low oxygen distillation process for rare earth smelting uses self-designed cooling and receiving systems and filtration systems to purify the distilled metal ytterbium while blocking radiant heat. Using a self-made high-purity lanthanum reducing agent, high-purity metallic ytterbium with a purity of more than 99.99% can be obtained by one distillation, and the direct yield of rare earth can reach up to 98%. The successful application of technology has promoted the successful localization of rare earth targets.
For users in the downstream of the industrial chain, based on the continuous updating of preparation technology, the purity of the product has been increased from "9995" to "9999", and the utilization rate of the original target material has been increased from 40% to 70% to 80%. Energy consumption and production costs have significantly decreased, allowing consumers to buy an electronic product with higher technological content at a lower price.
Behind the "realization of metal ytterbium substitution" is the scientific research climb path that the team has been tackling for many years. At the initial stage of research, the product is a new attempt proposed by the pilot base based on the downstream upgrading and updating needs of the panel industry.
Since 2013, this technology has started laboratory research;
By 2016, we have finally achieved technological breakthroughs and achievements transformation, and built a pilot production line with an annual output of 10 tons.
During the process, all the scientific research personnel of the project focused on the research, development and production of equipment on the production line, in addition to fine drilling and detailed research on the preparation technology. After continuous attempts, they finally achieved independent research, development and design of all the equipment on the production line.
Through continuous technological improvement and improvement, BTXT has now established an internationally leading production line of high-purity metallic ytterbium target materials for OLED (new organic luminescent materials), with a production capacity of about 50 tons/year. It has achieved low-cost, high-efficiency, and high-quality preparation technology for high-purity metallic ytterbium vapor plating materials, which not only solves the technical difficulties in the preparation of key materials of high-purity rare earth metals, It has also enhanced China's international position in the direction of high purity rare earth gold materials, with significant economic and social benefits.
Relying on advanced manufacturing processes and perfect production systems, the company has formed an industrial structure based on the key technologies for the preparation of dense ingots and large-sized targets of high-purity rare earth metal ytterbium, with the core of clean processing technology and oxidation prevention treatment technology of rare earth metal profiles, the focus of microstructure control technology of rare earth metal targets, and the expansion direction of terminal applications, to achieve the integrated development of the upstream, midstream, and downstream of high-purity metal ytterbium targets, Build industry-leading advantages in the entire industrial chain.
