Silicon micro powder, also known as quartz powder, is made of natural quartz (SiO2) or molten quartz (natural quartz after high temperature melting, cooling amorphous SiO2) by crushing, ball grinding (or vibration, airflow grinding), flotation, pickling purification, high purity water treatment and other multi-channel processing of micro powder Read More »

High purity polysilicon​ material is the basic raw material of information industry and solar photovoltaic power generation industry. Many developed countries regard it as a strategic material. Electronic-grade polysilicon is one of the most basic and main raw materials for manufacturing semiconductor silicon wafers, known as the "food" of the electronic information industry, with purity requirements of 99.999999999% ~ 99.999999999% (9N ~ 11N).

Semiconductor materials are a kind of electronic materials which have semiconductor properties and are used to make semiconductor devices. Semiconductor material is the foundation of semiconductor industry, and its development has great influence on the development of semiconductor technology. So what are the characteristics and applications of semiconductor materials? Read More »

Silicon metal, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. Industrial silicon is also used as an alloying agent for demanding silicon steel, smelting special steel and deoxidizer for non-iron based alloys. Industrial silicon can be drawn into monocrystalline silicon after a series of processes for use in electronics industry. Read More »

The surface properties of silicon are the key parameters to the success of the silicon direct bonding technique in the semiconductor industry. The hydrophilicity and roughness of silicon surfaces processed with three typical surface treatments in the direct bonding technique are systematically evalu Read More »

Before a semiconductor can be built, silicon must turn into a wafer. This begins with the growth of a silicon ingot. Growing a silicon ingot can take anywhere from one week to one month, depending on many factors, including size, quality, and the specification. Let’s take a deeper look at silicon wa Read More »

From the point of view of the demand side, the market prospect of polysilicon is good.First, the growth space of the photovoltaic industry is huge.Under the global market environment of low interest rate in 2020, a large number of overseas projects with financing locked in advance will be put into construction this year, and the global demand of photovoltaic industry will be soaring in 2021.Relevant data show that on a global scale, the demand for new installed PV capacity in 2021 will reach 160~170GW, and hence the demand for silicon wafers will reach 192~204GW, and the demand for polycrystalline silicon materials will reach 55.7~ 592,000 tons.
