After years of development, AHKS Advanced Materials Technology Group has formed high-end UTG, zirconium, silicon and titanium series products.
The [thickness] 30 μm high-strength flexible glass (UTG) developed by AHKS is the only national production and chemical ultra-thin flexible glass industry chain covering "high-strength glass – ultra-thin thin – high-precision post-processing" in China, with leading product performance.
At present, the company's ultra thin flexible glass UTG project (Phase I, 2 million pieces) has been delivered in batches, and the yield has maintained a good level. At the same time, the company is also developing different process routes, iterative product development, etc., to enhance the sustainable competitiveness of the project.
The company's ultra thin flexible glass UTG project phase II 15 million pieces project is expected to be put into operation at the beginning of 2023.
The company's one-time shaped glass related patents have been authorized in the first half of this year. One shot glass forming technology is to directly pull 30-70 μ m thick glass from the glass furnace and finish the UTG glass directly, without a large amount of chemical thinning of the glass.
As more yield will be lost in the glass thinning process, it is expected to further improve the overall yield of the company's UTG and reduce production costs after the successful mass production of the primary formed glass sheets.
The technology of one-time forming glass is extremely difficult. At present, only a few enterprises in the world have succeeded in mass production. After the successful mass production of one-time forming glass, the company will play a positive role in promoting the development of the company and even China's ultra-thin flexible glass industry.
Ultra thin flexible glass UTG is not only used for folding screen, but also for a wider range of purposes.
AHKS is working with partners to use ultra-thin glass on the screen to achieve directional sound production.
In terms of application materials, AHKS gives full play to its leading position in the fused zirconia industry, bases itself on zirconium products, expands silicon and titanium products, and transforms and upgrades its application fields from traditional ceramics and refractories to high-value electronic application materials such as chips, integrated circuit packaging, photovoltaic, semiconductor and bio medical treatment, with higher technology content and better market prospects.
Applied material products mainly focus on zirconium, silicon and titanium, based on zirconium products, such as fused zirconia, zirconium silicate and stabilized zirconium
On this basis, expand the product series, such as spherical quartz powder, high-purity synthetic silicon dioxide, nano barium titanate, rare earth polishing powder and other products.
Spherical materials (including spherical quartz powder and spherical aluminum oxide powder) are widely used in electronic packaging, semiconductor heat conduction, special ceramics and other high-tech fields. As a major participant in the formulation of Chinese national standards for spherical quartz powder, AHKS products have been fully recognized by downstream users, and its market share has gradually increased.
Spherical aluminum oxide powder has the characteristics of high sphericity, high strength and high thermal conductivity. It is used in the fields of thermal conductive adhesives, thermal conductive gaskets and special ceramics, and can also be used as thermal conductive materials for new energy batteries, with good market reaction.
AHKS has started the construction of 6000t/a spherical material project for electronic packaging. After the completion of the project, the total capacity will reach 14000 tons, becoming an incremental product of the application material sector.
High purity synthetic silica is mainly used in semiconductor, optical communication, photovoltaic and other fields. It is one of the key raw materials for the production of high-end semiconductor devices, and can be used as the inner layer material of N-type silicon wafer crucible, quartz glass tube/rod, quartz mound, etc.
At present, the company has an annual production capacity of 5000 tons of high-purity synthetic silica.
