The world's largest sapphire polycrystalline automated production line officially put into operation in Jingwu Town, Xiqing, Tianjin

Recently, the reporter learned from the Propaganda Department of Tianjin Xiqing District Committee that the new factory of Ruiwei Electronic Materials (Tianjin) Co., Ltd. was officially put into operation in Huigu Science and Technology Park, Xuefu High-tech Zone, Jingwu Town, and is the largest in the world with a single weight of 400 kg. Sapphire poly crystal held a new product launch.
Ruiwei Electronic Materials (Tianjin) Co., Ltd. is a national high-tech enterprise. The scientific and technological small and medium-sized enterprises recognized by the Tianjin Municipal Government are founded by experts from the National Thousand Talents Program. They are committed to the research and development of sapphire raw materials, namely high-purity and high-quality alumina. It has the world's largest sapphire polycrystalline automated production line with a monthly capacity of 100 tons. The company's product quality has reached the international first-class level. Since it was put on the market, it has been highly recognized by customers in China, South Korea and Russia, and its sales have grown rapidly.
The knowledge gas station sapphire is a single crystal of alumina, also known as corundum, which has a strong hardness. In terms of color, pure alumina crystals are transparent and colorless. When sapphire is growing in nature, When the crystal contains titanium ions (Ti3+) and iron ions (Fe3+), the crystal will appear blue, and the sapphire will be named. The main uses are as follows:
1. Large-size flat sapphire photoelectric window for aerospace;
2, the demand for sapphire materials in the field of residential semiconductor lighting, currently 80% of the world's LED sapphire substrate;
3. Large-size, high-quality sapphire military window and device;
4, used to prepare graphene;
5, for night vision through infrared equipment, infrared military equipment, satellite space technology.
In addition, the home button of the Apple phone and the protective layer of the camera are all sapphire.
