Market status of high purity quartz sand

The rapid development of modern science technology has put forward higher purity requirements for quartz, the basic raw material. The world recognized high purity ultra-high purity quartz raw material is an important basis for today's high-tech products a necessary part of the sustainable development of a country's high-tech. In Germany, ultra-high purity quartz raw materials have been listed as strategic materials export restrictions. High purity quartz sand is purified quartz sand processing, the useful minerals in the sand are highly dense, processed out. High purity quartz sand is the main raw material for the manufacture of silicon dioxide film, quartz glass, semiconductor silicon optical communication cables other high-performance materials, which can be widely used in modern science technology economic fields with high added value. Internationally, only seven companies in the United States, Japan, Britain, Germany France can produce these high-purity quartz sands. Among them, the production scale, technical equipment product quality, especially the detection accuracy, the United States UNIMIM company is in a leading position. Using quartz the unique pegystite deposit in SPRUCE PINE, North Carolina, United States, Unimin is in the lead in the production of high purity quartz sand through special processing chemical purification. In the early 1990s, China imported QUINTUS SAND Unimin Company in the United States, then related enterprises continued to import high purity quartz SAND Unimin Company in the United States (IOTA-STAND/ARD standard material, IOTA- 2, IOTA- 4, IOTA- 6, IOTA- 8 ultra high purity). Under the current circumstances, China's aerospace, satellite, missile, rocket, optical fiber, optical cable, special light source, microelectronics, fine chemical analytical chemistry other high-tech fields of rapid development, its level ranks among the best in the world. However, the development production of S high purity quartz sand is basically blank.

The data released by the national Customs, the import export of quartz sand in China in the past two years can be seen that China's exports are primary products, then look at the domestic market demand for high purity quartz sand: 1. The annual consumption of quartz glass is about 3000 tons. 2, electric light source :1000 tons/year. Quartz orange cochlea, only jinzhou 1555 plant 400 tons/year. 4. Estimated 30000 tons/year in other fields. It can be seen that such an advanced powerful pillar industry is built on the basis of relying on foreign raw materials, most of these products are deeply processed China's imported silicon ore. foreign sales are highly processed high purity quartz sand, the amount of several times. This has to be a tragedy.

The main problems in the research development of high purity quartz sand in China are as follows:

1. The country lacks a comprehensive unified standard for evaluating the quality of silicon raw materials. Raw material manufacturers can only supply raw materials according to the requirements of downstream manufacturers, it is difficult to maintain stable product quality.

2, tour manufacturers need high purity, super high purity quartz sand raw materials are willing to import abroad (the price of imported raw materials abroad is more than 3 times the price of domestic raw materials), think less risk, save trouble, few willing to assist raw material production enterprises to improve the quality of raw materials.

3, the business authorities did pay attention to high purity, super high purity quartz sand research work, that imported raw materials come quickly, the result is fast.

4. In the market economy environment, downstream production enterprises raw material production enterprises attach importance to the short-term benefits ignore the deep development prospective research work. In particular, the profits of raw material production enterprises are small, it is very difficult to solely rely on raw material enterprises to invest large funds in the research of high purity ultra-high purity quartz sand. Because the full set of laboratory testing equipment for high-purity ultra-high-purity quartz sand test research is as high as several million yuan, if all the imported price is higher (the accuracy of domestic equipment is good).

5, there is no high purity super high purity quartz sand production process equipment, imported abroad blocked, because foreign businessmen want to sell raw materials to China at a high price.

6. The competent authorities relevant enterprises are currently considering how to introduce the production technology equipment of semiconductor technology, such as ultra-high purity quartz glass optical fiber, instead of putting the development of raw materials on the agenda. To sum up, the problems mentioned above cannot be solved by raw material production enterprises alone. It is suggested that relevant business departments should pay attention to the research work of high purity ultra-high purity sand quartz according to the principle of sustainable development, so as to promote China's silicon raw material industry to catch up with exceed the international advanced level.
