China successfully developed high-performance transparent micro-nano crystal II generation electronic window material/micro-nano crystal glass Hay:B04HZQZ

Recently, the transparent micro-nano crystal Ⅱ generation electronic window material submitted by HZQZ Advanced Materials Technology Corporation adopts an advanced vector network analyzer-resonant cavity method and has been tested by a third party (China National Testing and Testing Holding Group Co., Ltd.). The dielectric constant (2.64GHz) is 7.25, and the dielectric loss (2.64GHz) is 0.0070. Compared with the products of world-class panel manufacturers, the dielectric constant is reduced from 11 to 7.25, which is a reduction of 34%; the dielectric loss is reduced from 0.03 to 0.007, which is a reduction of 77%.


The new micro-nano crystal Ⅱ material (micro-nano crystal glass) developed by HZQZ is mainly used for mobile phone cover and back panel. This material is used for mobile phone covers and back panels, with less data and signal loss and faster aging, and will become the first choice for 5G mobile phones.

Performance is the world's first


Dr. Zhao, CTO of HZQZ, began researching and developing glass-ceramics 10 years ago. He has the title of "Father of Chinese Glass-Ceramics" and is the winner of China's National Science and Technology Progress Award and Technology Invention Award.

The micro-nano crystal glass produced by HZQZ is the innovative result of Dr. Zhao's scientific research team. Based on the research of glass-ceramics, it has found a unique formula, developed a micro-nano crystal material, and successfully put into production the second generation of transparent micro-nano crystal The electronic display new material production line achieves industrialized mass production.

It is precisely because of the low dielectric loss of micro-nanocrystalline glass that it is used to make mobile phone cover and back panel, which will have better signal reception and transmission quality. It will become the first choice for electronic window materials in the 5G era, and it will also make wireless charging of mobile phones possible.

In fact, micro-nano crystal glass not only has the characteristics of low dielectric constant and low dielectric loss, but also has the characteristics of high hardness, drop resistance, and high light transmittance.


In addition to mobile phones, it can also be used as automotive glass and photovoltaic glass in the future


Display technology is one of the core technologies of the electronic information industry. China contributes 60% of display panels, 70% of smart TVs, 75% of smart phones and 90% of computers to the world. However, its key technologies and markets have long been monopolized by foreign manufacturers such as Corning, while micro-nanocrystalline glass is completely monopolized. It is independently researched and developed by HZQZ, has complete independent intellectual property rights, and has superior overall performance, and is expected to gradually form a domestic substitute.


The superior performance of micro-nano crystals will better realize applications such as wireless entertainment, cloud VR/AR, social networking, and personal AI assistance in 5G mobile phones, smart wearables, high-definition displays and other terminals in the 5G era; its high transmittance , High strength, high wear resistance and other properties will become important and indispensable structural and functional materials for 5G mobile phones and display terminals.

"Another important application scenario is that micro-nano crystals will be promoted in the display of automobiles, airplanes, ships, windshields and other fields. Because of the high strength, high wear resistance, and high light transmittance of micro-nano crystal glass, automotive The windshield can be made thinner and stronger. The weight of the glass of a car is 35 kg on average. If the weight of the car glass can be reduced to 20 kg, the reduced 15 kg will be used for the battery of the new energy vehicle. Ability will be greatly enhanced.
