According to a report released by the American Semiconductor Industry Association (SIA), the global semiconductor market reached a record high of US $555.9 billion in 2021, an increase of 26.2% compared with US $440.4 billion in 2020. China remains the world's largest market for semiconductor applications, with total sales reaching US $192.5 billion in 2021, an increase of 27.1% over the same period last year. According to Philippine's prospectus, for every 100 million US dollars of electronic information products, the average consumption of quartz glass materials is 500000 US dollars. The global quartz glass market is expected to reach 31.66-3.312 billion US dollars in 2022-2023. China's quartz glass market is expected to reach 1.096-1.146 billion US dollars.



Optical communication field.
Quartz rod is the main raw material for the manufacture of optical fiber. More than 95% of the components in the optical fiber preform are made of high-purity quartz glass, and a large number of quartz glass materials, such as holding rods and quartz cups, need to be consumed in the optical fiber production process, such as optical fiber rods and wire drawing.
The construction of 5G promotes the rapid development of optical fiber and cable market. The amount of optical fiber under the 5G network architecture will be 16 times that of the 4G network, and the scale of the base station in the 5G era will be 2-3 times that of the 4G base station. The interconnection of base stations will bring more demand to the optical fiber and cable market. The three major operators actively strengthen the procurement of optical fiber and cable to promote the commercial process of 5G. According to CRU data, it is estimated that the demand for optical fiber and cable in China will reach 261 million core kilometers in 2022.



Optical field.
Synthetic quartz glass materials are used as lenses and prisms in high-end optics, TFT-LCD high-definition displays and photomask substrates for IC. According to a report released by Zhiyan Consulting, the main revenue of China's optical instrument manufacturing industry in 2021 was 85.21 billion yuan, an increase of 4% over the same period last year. With the accelerated development of 5G, AIoT technology and global digitization process, the penetration of consumer electronic products continues to improve, new scenarios and new applications promote the diversified development of IT products, and the rapid growth of the new energy vehicle market leads to the continuous growth of display panel demand. In 2021, the output value and output of the global new display industry have reached a new high. According to the data of the liquid crystal branch of China Optoelectronics Industry Association (CODA), the global output value of the new display panel in 2021 is about 150 billion US dollars.



Summary.
Quartz glass products are key consumables and raw materials in various fields, which restrict the production of downstream industries, and there is no substitute for products at present, so the demand for quartz glass exists for a long time. With the accelerated development of downstream industries, especially the semiconductor and photovoltaic industries, the prosperity of quartz glass industry will continue to improve.
