FAQ

Q1

What are the applications of Silicon Dioxide SiO2 powder in the rubber industry?

Answer : Silicon Dioxide SiO2 powder is mainly used as a filler and thickener in the rubber industry. It can increase the hardness, wear resistance and aging resistance of rubber, and improve the mechanical strength and dimensional stability of rubber products. In addition, SiO2 powder can also improve the processing performance of rubber, such as improving mixing efficiency and reducing energy consumption.

Q2

Why is Silicon Dioxide SiO2 powder so important in the electronics industry?

Answer : The reason why Silicon Dioxide SiO2 powder is important in the electronics industry is because it has excellent insulation performance and low coefficient of thermal expansion. This makes SiO2 powder an indispensable material in electronic products such as integrated circuit substrates, fiber optic communication devices, and solar cells. In addition, SiO2 powder can also be used to make electronic packaging materials, capacitors, resistors and other electronic components, providing strong guarantees for the stable performance and reliability of electronic products.

Q3

How to prepare high-purity Silicon Dioxide SiO2 powder?

Answer : The preparation of high-purity Silicon Dioxide SiO2 powder is usually achieved through methods such as chemical vapor deposition (CVD) or physical vapor deposition (PVD). These methods can react silicon and oxygen sources to generate SiO2 powder at high temperatures, and obtain high-purity, fine-grained, and uniform SiO2 powder by controlling reaction conditions and subsequent treatment processes. In addition, SiO2 powder can also be prepared by sol-gel method, melting method and other preparation technologies.

Q4

What are the environmental impacts of Silicon Dioxide SiO2 powder?

Answer : Silicon Dioxide SiO2 powder itself has a relatively small impact on the environment because it is a non-toxic, odorless, and non radioactive substance. However, during the production and use of SiO2 powder, certain waste and emissions may be generated, such as wastewater and exhaust gas. If these wastes and emissions are directly discharged into the environment without treatment, they may cause certain pollution to water, soil, and air. Therefore, in the production and use of SiO2 powder, appropriate environmental protection measures and treatment technologies need to be taken to ensure the standard discharge and resource utilization of waste and emissions.

Q5

What are the unique features of Silicon Dioxide SiO2 powder compared to other types of oxide powders?

Answer : Silicon Dioxide SiO2 powder has unique physical and chemical properties compared to other types of oxide powders. Firstly, SiO2 powder has a high melting point and high hardness, which allows it to maintain stable performance even in high temperatures and harsh environments. Secondly, SiO2 powder has good insulation and low coefficient of thermal expansion, which makes it have broad application prospects in the fields of electronics and communication. In addition, SiO2 powder also has the characteristics of high purity, fine particle size, and good uniformity, which can meet the high requirements of many high-tech applications for material quality and performance. These unique features give SiO2 powder irreplaceable advantages and application value in many fields.
