Monocrystalline silicon production process (1) Polaris Solar Photovoltaic Network Keywords: single crystal silicon silicon single crystal Monocrystalline silicon is usually produced by first producing polycrystalline silicon or amorphous silicon, and then growing rod-shaped single crystal silicon from the melt by a Czochralski method or a suspension zone melting method. When the molten elemental silicon solidifies, the silicon atoms are arranged in a diamond lattice to form a plurality of...
Nano titanium dioxide photocatalyst Nano titanium dioxide photocatalyst The main component of the photocatalyst is ultra-nano-molecular nano-titanium dioxide, which is a material with a small pore size of 2-5 nm. 700m2 /g is an inorganic acid amorphous film formed of titanic acid or silicic acid, and the solid matter particle size in the solution is distributed at about 10 nm. Different from the principle of catalysis of ultraviolet light irradiation with titanium oxide photocatalyst, this...
The metal cutting industry is a very important sector in the national economy, and it is inseparable from all walks of life. According to the statistics of 1988, the cost of cutting and processing in the United States is as high as 100 billion US dollars per year, of which the cost of cutting tools is 1 billion US dollars. With the development of the new technology revolution, it is required to continuously improve the cutting processing productivity and reduce the production cost, especially...
At present, the demand for silicon micropowder in the international and domestic markets is large, and foreign merchants purchase a large amount of silicon micropowder in China. At present, the price of domestic silicon micropowder is nearly 2,000 yuan per ton. At present, most industrial silicon plants in China can recover one ton of silicon micropowder for every three tons of industrial silicon. The production of 6300 industrial silicon furnace can recover 3 to 4 tons of silicon micro-powder...

Summary of polysilicon and monocrystalline silicon for the recent warming trend dispute. Silicon has two isomorphs, crystalline and amorphous. Crystalline silicon is divided into single crystal silicon and polycrystalline silicon, both of which have a diamond lattice, the crystal is hard and brittle, has metallic luster, can conduct electricity, but the conductivity is not as good as metal... Recently, the debate over polysilicon and monocrystalline silicon has been on the rise. Silicon has two...
The 2018 National Titanium Dioxide Industry Annual Meeting, co-sponsored by the National Chemical Industry Productivity Promotion Center Titanium White Center, Titanium Dioxide Industry Technology Innovation Strategic Alliance and China Coatings Industry Association Titanium Dioxide Branch, was held in Sichuan recently. The experts at the meeting believed that the titanium dioxide industry entered a period of steady development this year. According to Bi Sheng, director of the Titanium Dioxide...
Abstract This week, the market price of silicon materials is stable, and the price of domestic polysilicon materials is basically unchanged compared with the beginning of the week. The price of second-level materials has not changed much compared with the beginning of the week. In terms of imported materials, this week, the exchange rate of the US dollar has decreased. Impact, the price of imported silicon material declined slightly compared with the beginning of the week. This week, the price...
At the end of the year, the titanium dioxide market is still not improving. At present, the mainstream price of domestic sulphuric acid rutile is 15300~17000 yuan/ton, and the mainstream of anatase titanium dioxide is 12800~14000 yuan/ton. It is understood that in the early period of North China and East China, due to smog weather, under the influence of environmental protection and high pressure, the demand for raw material titanium dioxide in the downstream of coatings and papermaking was...
In recent years, the global supply of silicon wafers has been insufficient, resulting in orders for 8-inch and 12-inch silicon wafers having reached the first half of 2019 and the end of the year. At present, a number of domestic silicon wafer projects have begun, and it is expected to be able to break the import dependence and have sufficient capacity to meet market demand. Knowledge point 1: What is a silicon wafer? The silicon wafer is purified by silicon (99.999%), and then the pure silicon...
After the holiday, some domestic enterprises and merchants have not resumed work, but the titanium dioxide market has already set off a wave of price increases. On February 12th, Longsheng Lilian Group, which has the largest production capacity in China, announced that it will raise the sales price of titanium dioxide from now on. The domestic customers will increase the price by 500 yuan/ton on the basis of the original price, and the international customers will raise the price by US$100/ton....
The difference between single crystal silicon and polycrystalline silicon is that when the molten elemental silicon solidifies, the silicon atoms are arranged in a diamond crystal lattice into a plurality of crystal nuclei, and if these crystal nuclei grow into crystal grains having the same crystal plane orientation, single crystal silicon is formed. If these nuclei grow into crystal grains having different crystal plane orientations, polycrystalline silicon is formed. The difference between...
