Product Description
Manufacturer wholesale Manufacturing pure silicon granules, silvery gray, metallic silicon, suitable for welding materials, CAS 7440-21-3
Explain:
1.Silicon particles are the raw material for manufacturing semiconductors and solar panels, obtained through the extraction and purification from sources like quartz rock.
2.Silicon particles, or silicon powders/micro/nanoparticles, have numerous advantages that render them indispensable across various sectors, including electronics, energy, and materials science. Key benefits include their high surface area to volume ratio, superior electrical and thermal conductivity, and remarkable chemical stability. These properties significantly enhance their utility, particularly in semiconductor applications where they are crucial for the development of high-efficiency solar cells, advanced batteries, and sophisticated integrated circuits. Moreover, their capacity for functionalization or doping facilitates their use in a wide array of technological and scientific applications, further amplifying their versatility and value.
3. In terms of silicon granules' properties: the melting point is approximately 1410°C (2570°F), the boiling point is around 2355°C (4271°F), silicon is virtually insoluble in water at room temperature, and its hardness on the Mohs scale is roughly 7, indicating it is harder than glass but softer than quartz.
Properties:
Properties of silicon particles include a high melting point, typically above 1410°C, good semiconductor performance making them widely used in the electronics and photovoltaic industries. They exhibit good chemical stability, rarely reacting with most substances at room temperature, but can react with non-metal elements such as oxygen and chlorine at high temperatures. Silicon particles also demonstrate excellent thermal stability, maintaining their physical and chemical properties for long periods at high temperatures. Moreover, by doping, their conductivity can be adjusted to produce either P-type or N-type semiconductors, which is crucial for the fabrication of integrated circuits and solar cells.
Storage conditions:
Tungsten powder shall be stored in a dry, cool and sealed environment and shall not be exposed to the air. In addition, heavy pressure shall be avoided and it shall be transported as ordinary goods.
