On December 15th, the SH Group held a new material launch conference in Shenzhen EPC Cultural Center. It released its newly developed "three" for smart terminal ceramic structural parts and mobile phone ceramic back cover products. Fire Phoenix "diamond crystal zirconium ceramic material.
According to reports, "Fire Phoenix" diamond-crystal zirconium ceramic material is a new material specially created for mobile phone back cover applications. It has excellent characteristics such as ultra-high bending strength, extraordinary fracture toughness, good rigidity, and high wear resistance.
Ultra-high flexural strength: Ultra-high flexural strength exceeding 1200Mpa, compared with 552Mpa of tempered glass, has obvious advantages.
Extraordinary fracture toughness: 10 times the fracture toughness of glass, up to 8 ± 2MPa * m1 / 2, while tempered glass is 0.69 MPa * m1 / 2, which has a stronger ability to resist crack propagation.
Good rigidity: up to 200GPa elastic modulus, tempered glass is 76.7GPa, which has better resistance to elastic deformation.
High abrasion resistance: Mohs hardness of 8-8.5, close to that of sapphire, while tempered glass is 5-6, which has obvious advantages and can resist the friction damage of most substances in daily life.
No shielding of signals: lower dielectric loss than tempered glass, reflecting better electrical performance, more adaptable to the future 5G era.
"SH fire phoenix" diamond crystal zirconium ceramic materials can currently produce black, solid white, transparent white and color and other colors, used in mobile phone back cover can meet the personalized needs of mobile phone users. In addition, the Sanhuan Group is also able to achieve the mass production of ceramics, which meets various conditions applied to the back cover of mobile phones.
It is worth mentioning that after introducing the "three ring fire phoenix" diamond crystal zirconium ceramic materials, Yang Shuangjie, deputy general manager of the mobile phone division of the SH group, demonstrated the drop test of the whole machine on the spot. The back cover of the ceramic mobile phone made of zirconium crystal ceramic materials passed the drop tests on the back, edges, and corners of the machine at heights of 1 m, 1.2 m, and 1.5 m, respectively, and more intuitively broke everyone's fragility of ceramics. The concept also verifies the superior performance of the "three-ring fire phoenix" ceramic material.
Zhang Wanzhen, Chairman of the SH Group, attended the press conference and delivered a speech. He believes that ceramic materials have four characteristics. One is that at 5G high frequency, its dielectric loss is nearly 20 times lower than that of glass, the high frequency loss is lower, and the signal reception is clearer. The second is crystal drilling. Zirconium material has a high affinity with human skin, with a sense of beauty and feel; the third is that diamond crystal zirconium ceramics can be processed into any shape, including unibody shapes that are difficult to achieve with glass; the fourth is that the strength and hardness of the ceramic back cover is twice that of glass Not easy to be scratched. He predicted that the characteristics of the new ceramic material will be one of the best choices for future mobile phones, and the mobile phone industry has also brought the Sanhuan Group into a new application area.
It is understood that the SH Group integrates research and development and manufacturing of materials, products and equipment, and its products cover application areas such as optical communications, electronics, electrical engineering, machinery, energy conservation and environmental protection, new energy, biology and fashion, including fiber optic connector ceramic ferrules, The production and sales of alumina ceramic substrates and resistor substrates are among the highest in the world.
With its solid ceramic powder research and development foundation, complete molding process and sintering process, Sanhuan Group developed and mass-produced ceramic structural parts for smart terminals and mobile phone back covers in 2015. They are Xiaomi, Huawei, OPPO, vivo , OnePlus and other domestic first-tier mobile phone terminal manufacturers supply 2.5D, 3D, unibody mobile phone ceramic back covers or fingerprint recognition ceramic covers with different structural designs, which opened the door to the application of ceramic materials in smart terminal electronics. The field has set off a material revolution on metals, glass and ceramics.
From Professor Xie Zhipeng of the School of Materials, Tsinghua University, partner of Hong Kong alt + design, internationally renowned Chinese designer Zhang Jianpeng, Prof. Yongling Ban from the University of Electronic Science and Technology of China, Dr. Yan Zhanmeng, Director of Counterpoint and Greater China, and chief analyst of Xingye Securities Electronics Industry From the perspective of various professions, we shared the cutting-edge technology and industry trends, and explored the brilliant sparks from the collision of ceramics and mobile phones.
"The ceramic back cover is gradually recognized by consumers and mobile phone brand manufacturers. Apple, Samsung, and domestic Xiaomi, Huawei, OPPO, vivo, etc. have all shown great interest in ceramics." Dr. Liu Liang said that it is expected that high-end ceramics for smart phones in 2019 Back cover penetration is expected to reach 10%.
