With the rapid development of China's electronics industry and photovoltaic industry, the market's demand for high-purity ammonia has grown strongly. To comply with this market trend, Japan Showa Denko, Sumitomo Refine and German Linde recently set up production bases in China, while expanding the production capacity of Japan and Taiwan, and increasing logistics facilities such as warehousing and distribution to meet the market. The strong demand. As a film forming gas for a nitride film in the electronic industry, high-purity ammonia is widely used in the production of semiconductors, liquid crystal panels, and gallium nitride-based LEDs, and applications in the field of polycrystalline silicon solar cells are also increasing.

In June this year, Japan Showa Denko announced that in order to meet the increasing demand of the electronics industry, it will carry out capacity expansion and reconstruction of high-purity synthetic ammonia production facilities located in China, Japan, and Taiwan, China, and increase production capacity by 2,000 tons/year. Among them, the production capacity of the Kawasaki Plant in Japan will be expanded from 1,000 tons per year to 1,500 tons per year. The production capacity of Showa Chemicals in Taiwan will be expanded from 1,500 tons per year to 2,500 tons per year. Showa Electronics, Juhua, Zhejiang, China The capacity of the material affiliates has been expanded from 500 tons/year to 1,000 tons/year. The three capacity expansion projects will be completed by the end of 2011. By expanding capacity, Showa Denko's high-purity ammonia production capacity will be increased to 5,000 tons/year. According to Showa Denko's forecast, the electronics industry market in East Asia will further increase. In order to ensure a stable supply of high-purity ammonia, Showa Denko has decided to expand its capacity for a number of projects.
Japan's Sumitomo Seiki Co., Ltd. also announced recently that it has established a subsidiary company, Sujing Technology (Yangzhou) Co., Ltd. in Yangzhou Chemical Park, Jiangsu, to produce high-purity ammonia. Sumitomo Seimitsu Co., Ltd. stated that LED and LCD are the most commonly used advanced optoelectronic technologies for the production of light-emitting devices in the world, and high-purity ammonia is a very important raw material. However, at present, China is still unable to meet relevant process requirements in the production of high-purity ammonia. . With the increasing demand for LED and LCD in the Chinese market, the demand for high-purity ammonia will also increase dramatically. Therefore, the company decided to build a production plant with a production capacity of 3,000 tons/year. It is expected that it will be completed and put into operation in 2012. At the same time, the company will also expand production capacity to meet demand in accordance with demand growth. It is understood that Sumitomo Precision Chemicals has established sub-plants for producing high-purity ammonia in Japan, South Korea, and China Taiwan. The establishment of a subsidiary in mainland China is also a measure taken in accordance with the needs of the Asian market.
Linde, the world-famous industrial gas producer, announced through its subsidiary Lianhua Linde in December last year that the company's ultra-high-purity ammonia plant built in the southeastern coastal city of Xiamen has been successfully put into operation to further strengthen Lianhualin. Germany's commitment to meet the needs of the LED manufacturing industry. This is the first ultra-high purity ammonia plant in China that has been put into production. The annual production capacity of the plant is 500 tons of ultra-high purity ammonia with a purity of 7N (99.99999%). Lianhua Linde is a joint venture established by the Linde Group and China Taiwan’s Lianhua Shentong Group. Currently Linde has signed gas supply contracts with six major LED manufacturers in China. It also includes three companies that are invested by Taiwan companies in China.
