(Silicon Si powder CAS 7440-21-3)

Overview Of Silicon Si Powder

Silicon Si Powder, also known as micro silicon powder or silica fume. It is a powdery material formed by collecting and processing the smoke and dust that escapes with the exhaust gas during the high-temperature melting of industrial silicon and ferrosilicon in an industrial electric furnace through a special capture device. The SiO ₂ content in this type of smoke and dust accounts for about 90% of the total smoke and dust, and its particle size is very small, with an average particle size of almost nanometer level.

Silicon powder is a kind of new environment-friendly inorganic non-metallic functional powder material, which is selected from natural fused crystalline quartz or fused silica as raw material after rough grinding, purification, wet/dry ball milling or airflow milling and further processing according to the liquid or aerodynamic fine classification process.

FAQ

Q1

What are the main uses of silicon powder?

Answer: The main uses of silicon powder include as a deoxidizer and alloy additive in the steel and metallurgical industries, raw materials for ceramics and refractory materials, organic silicon compound raw materials in the chemical industry, semiconductor materials in the electronic industry, and concrete admixtures in the construction industry.

Q2

In what fields can silicon powder be used as a semiconductor material?

Answer: Silicon powder can be used as a semiconductor material in the electronics industry, especially in manufacturing integrated circuits and solar cells. Pure monocrystalline silicon is the key material for manufacturing these devices.

Q3

Is silicon powder harmful to human health?

Answer: Silicon powder is not directly toxic to the human body, but it is important to avoid prolonged inhalation or contact when handling silicon powder. Long-term exposure to a silica dust environment may lead to silicosis, an occupational disease similar to pneumoconiosis. Therefore, appropriate protective measures should be taken when handling silicon powder.

Q4

Is silicon powder flammable and explosive?

Answer: Silicon powder may have flammable and explosive properties under certain conditions. Especially when silicon powder mixes with air to form a certain dust cloud concentration, it may cause an explosion when encountering a fire source or high temperature. Therefore, when handling silicon powder, it should be ensured to operate in a well-ventilated environment and away from ignition sources and static sparks.

Q5

How to store silicon powder to ensure its quality?

Answer: To ensure the quality of silicon powder, it should be stored in a dry and ventilated place, away from ignition sources and flammable materials. The storage container should be well sealed to prevent the reaction between silicon powder and moisture in the air. In addition, prolonged exposure to high temperatures or humid environments should be avoided to avoid affecting its performance.

Q6

What is the impact of silicon powder on the environment?

Answer: Silicon powder has a relatively small environmental impact, but attention should be paid to avoiding pollution during treatment and use. For example, discarded silicon powder must be properly disposed of to prevent environmental pollution. In addition, the silicon dust generated during the production process may impact air quality, so appropriate measures must be taken to control and treat it.
