"High-refractive-index transparent ceramic materials will provide a new technical solution for high-definition ultra-thin imaging systems in AR/VR, mobile phones, vehicle cameras and other fields in the future, and at the same time provide basic material support for the underlying hard technology of the Metaverse"
ZKHY Advanced Ceramic Material Technology Corporation is hatched from the scientific research achievements of China SSL Transparent Ceramics Laboratory. With high-refractive transparent ceramic technology as the core, it has carried out a series of structural design and independent research and development of transparent ceramic material systems. Based on the team's experience in transparent ceramic materials With the advantages of technology accumulated in the field for more than 20 years, it provides customers with high-end super-hard transparent cover plates that replace sapphire glass and all-crystalline materials required for high-refractive lenses.
Technology
ZKHY has created an original ultra-high refractive index transparent ceramic normal pressure sintering preparation technology, which supports the preparation of different refractive index modulation transparent ceramic material systems. Compared with the common glass/sapphire cover plates and lenses in the consumer electronics market, the transparent ceramics developed by the company have a significantly higher refractive index and a Mohs hardness of >7. Thinner/clearer/lighter VR lenses all have significant value.
In addition, compared with traditional products, the company's transparent ceramic products have the following obvious technical advantages:
① It can replace high-refractive glass (n: 1.4~1.9): the refractive index of the company's transparent ceramic products is as high as 1.8~2.4 (adjustable), which can be used in high-definition ultra-thin lens modules, VR optical waveguide substrates, laser holographic imaging, optical The switch field has important application value;
② It can replace high-hardness sapphire (Mohs hardness: 9): the hardness of the company's transparent ceramic products is greater than that of quartz sand dust (Mohs hardness: 7), and can be lower than 9, which can reliably achieve scratch resistance on the surface of transparent materials Injury function while taking into account the low processing cost;
③ Near-net shaping of special-shaped parts, thus significantly reducing post-processing cost and cycle;
④ The company's products can be modulated in optical properties, including the modulation of refractive index, transmittance, and emission spectrum, as well as the modulation of product mechanical properties, including modulation of hardness, strength, toughness, etc.;
⑤ It can be designed to realize the unique photochromic function of the product. A certain product independently developed by the company is the most significant photochromic material system (discoloration rate R>64%) among the known inorganic non-metallic materials. The color and depth can be optically erased, and it has important application value in multiple anti-counterfeiting, optical erasing and other fields.
Products
ZKHY can design and customize transparent ceramic materials with different optical properties (refractive index, transmittance, luminescence, discoloration, etc.) and mechanical properties (hardness, strength, toughness, etc.) according to the actual needs of customers. The company supports nearly ten Simultaneous development of various material systems, and can develop corresponding materials in a targeted manner according to different product requirements to meet customer performance requirements. The company's products are mainly used in the field of electronic consumer goods such as mobile phones and watches and in the field of VR.
The transparent ceramic material products developed by ZKHY cover multiple high-value application scenarios. Market applications cover mobile phones, watches, VR, automotive electronics, lasers and other fields, creating a variety of business models to develop.
Customers
At present, ZKHY is conducting business cooperation with a number of leading companies in consumer electronics and lenses at home and abroad. At present, more than ten products have achieved commercial production. One of the most representative transparent ceramic cover products, as a realization of the engineering application of high-refractive transparent ceramics in electronic consumer cover materials, can provide a low-cost anti-scratch screen cover material.
As a new technology, the realization and introduction of new transparent ceramic materials in many products will take time, and customers have extremely high requirements for the reliability and yield of such materials in the mass production process, so I hope the industry and capital market will give this The industry has ample time and opportunity to explore the development direction of new technologies. In addition, it is expected that such high-refractive transparent ceramic materials will also have a greater opportunity to become the underlying hard technology support material of the Metaverse in the future, with broad development and usable space.
R&D team
The core R&D team of ZKHY is mainly led by the academician of the Chinese Academy of Sciences as the chief scientist, and is led by Professor Cao Yongge, the winner of the Hundred Talents Program of the Chinese Academy of Sciences and the leader of the Pearl River team.
Dr. Cao has been engaged in the research of optical functional transparent ceramics for a long time. He has successively worked in the Institute of Physics, Chinese Academy of Sciences, the University of Hong Kong, Nagoya Institute of Technology/AIST, Fujian Institute of Physics, Chinese Academy of Sciences, and Renmin University of China. In 2020, he will return to the Institute of Physics, Chinese Academy of Sciences as a researcher and doctoral student. Instructor, head of the transparent ceramic team of the Pearl River Delta Research Department (Songshan Lake Materials Laboratory) of the Institute of Physics, has accumulated more than 20 years of research and development experience in the field of transparent ceramics and nearly ten years of experience in the industrialization of transparent ceramics.
