The Quartz Industry Is Booming

Quartz is the main mineral component of silica ore and one of the main rock-forming minerals. It has stable physical and chemical properties and many excellent properties.

The whole quartz industry chain is quartz sand, quartz materials, quartz products in turn, and the last is the terminal application. Quartz sand, quartz ore after physical and chemical dressing and roasting to get high-purity quartz sand, due to the processing technology such as mineral dressing and few high-quality ores, only a few enterprises in the world have the ability to mass production of high-purity quartz sand. Quartz materials can be prepared by natural quartz processing or artificial synthesis, of which natural quartz processing has electric melting and gas melting processes. Electric melting products are mainly used in semiconductor diffusion and other high-temperature areas, while gas melting products are used in low temperature, such as the etching process.

Upstream: The Scale Production of High Purity Quartz Sand Enterprises Are Very Few

At present, there are two main methods to obtain high purity quartz sand. One is through artificial synthesis. This method consumes a lot of energy and costs a lot, so it is not suitable for large-scale production. The second is the processing of quartz ore. This method has higher requirements on the production phase and processing technology of quartz ore. Although quartz ore is abundant in the world, the quartz ore resources with high purity, good quality, and large reserves are relatively scarce.

High purity quartz raw material distribution is uneven, domestic high-quality ore accounts for less than 1%. High purity quartz raw material, that is, the existing mature processing technology can purify the silicon dioxide content to 99.9% and above the natural quartz ore. Preparation of high purity quartz sand is one of the best raw material is a natural crystal, but its reserves are scarce, and with the mining, resources gradually dry up, uneven distribution, in addition to a few countries such as Brazil, Madagascar, South Africa and other regions, other nations reserves of natural crystal, small size, less origin, performance is not stable, it is difficult to mass production. High purity quartz raw materials, on the other hand, the metallogenic conditions demanding, in quartz mineral species, vein quartz best quality, the color is pure white, oily luster, high purity, mineral composition is basically quartz, silica content is above 99%, but only 0.93% in the quartz ore resources in China, quartz ore resources in China really can be used as high purity quartz glass raw materials of mineral reserves, small size.

At present, there are only a few enterprises in the world capable of mass production of high purity quartz sand, especially Uni-Ming, Norway TQC, and quartz shares as the main representatives. Of American unity of high purity quartz sand ore for North Carolina Spruce, Pine region granitic pegmatite, is the only global ALe Haney green schist movement affected the high purity quartz ore deposit, with ore-body scale, less impurity, ore fluid in quartz the advantages of stable quality, unity is the Ming company production of quartz sand with high purity quartz sand markets around the world share one of the reasons has the absolute monopoly advantage.

Downstream: Semiconductor Is the Main Application, And Optical Fiber, Photovoltaic Fields Have Great Development Potential

Quartz glass is a kind of special industrial technology glass composed of Si02 (Si02), which has a series of excellent physical and chemical properties. Quartz glass materials and products are consumables. The downstream application of the medium-low end light source industry is moving towards the high-end field, while the semiconductor quartz industry occupies the main share. In 2018, in the global quartz industry downstream market, the semiconductor sector has the highest demand, accounting for 65% of the market demand of 20.6 billion yuan, followed by the optical fiber sector, accounting for 14%. Semiconductor, photovoltaic, and optical fiber industries, driven by policies and emerging technologies, are developing rapidly.

Emerging Application Development Superimposed Domestic Substitution, The Semiconductor Industry Continues to Develop

With the development of the Internet of Things, blockchain, automotive electronics, driverless cars, and 5G, the semiconductor industry is expected to maintain a high boom. At present, China's semiconductor self-sufficiency rate is less than 20%, facing the complex international environment and under the pressure of others, domestic substitution space is large. In recent years, industrial policies have been issued at the national level to strongly support the development of the integrated circuit industry. The overall planning, national investment fund for the integrated circuit industry, and preferential income tax policies will guide and accelerate the development of China's semiconductor industry, and also drive the further growth of the market scale of electronic grade quartz products.

Influenced by Policies And 5G Technology, Optical Fiber Has A Broad Prospect

Quartz glass material is the main auxiliary material for fiber prefabrication rod and fiber drawing process. According to the data, the global demand for optical cable in 2019 is 520 million core kilometers, and 338 million core kilometers in China. By governments to optical fiber cable industry continued policy support, the mobile Internet high-speed growth and 5 g technology application and optical fiber to the home, the influence of such factors as the global optical fiber cable industry will continue to maintain steady growth, the market demand for optical fiber preform, optical fiber and optical cable will further increase, industry will usher in a new round of development opportunities. In 2015, the Ministry of Commerce imposed an anti-dumping duty of 8%-41.7% on the imports of optical rods from the United States and Japan, which further promoted the production capacity of domestic optical rods. At present, the self-sufficiency rate of domestic optical rods has reached nearly 80%, which also makes the support of quartz glass raw materials and auxiliary materials in the field of optical communication in China develop towards high-end.

Quartz crucible made of quartz glass is a quartz vessel necessary for the production of monocrystalline silicon. It is a consumable vessel for the production of monocrystalline silicon. A quartz crucible is used for each furnace of monocrystalline silicon production. With the development of the new energy industry and the support of national macro policies, the photovoltaic industry has been developing rapidly in the past few years. Data shows that in 2019, the new installed capacity of the global photovoltaic industry is about 114.9GW, and the new installed capacity of the domestic photovoltaic industry is about 30.1GW. The total installed capacity is 204.7GW, accounting for almost one-third of the global installed capacity of photovoltaic. China has become the world's largest photovoltaic market. Since 2013, relying on the national policy guidance of "One Belt and One Road", Chinese photovoltaic enterprises have been continuously expanding their industrial scale, increasing their industrial concentration and technological level, and many photovoltaic enterprises have begun to deploy overseas markets. The rapid development of the photovoltaic industry directly stimulated and drove the market demand for quartz crucible products.
