Introduction

Metallic silicon powder and silicon powder are both in the powder state of silicon and have significant differences in morphology, chemical properties, physical properties and uses. Metallic silicon powder is an amorphous substance composed of silicon and carbon elements, while silicone powder is a powder with high silica content, very fine particles, and high activity recovered during the production of metallic silicon or iron alloys. In the fields of metallurgy, chemistry and construction, both types of silicon powder are widely used, but they differ in specific application scenarios and effects.

The product differences between metallic silicon powder and silicon powder


Metallic silicon powder is a product produced during the metallurgical process and is mainly used to produce metallic silicon or iron alloys. It has the characteristics of high melting point, high resistivity, wear resistance, corrosion resistance, etc., and can be used in industrial fields such as casting, steelmaking, and refractory materials. In the field of refractory materials, metallic silicon powder can be used as raw material to prepare high-performance refractory castables, prefabricated parts, etc. In addition, it is also used to produce core components of electronic equipment such as semiconductor devices and power rectifiers.

In contrast, silica powder is a polycrystalline powder composed of silica with smaller grain size and finer particles, usually less than 0.1 microns. Silicon powder has strong activity and can react with a variety of metals and non-metallic substances at high temperatures to produce metallic silicon or silicates. In the chemical industry, silicon powder is widely used in the production of silicone monomers and polymers, such as silicone oil, silicone rubber, silicone resin, etc. In addition, silica powder is also used to produce inorganic compounds such as silica and silicates, as well as building materials such as synthetic glass and cement.

In the field of building materials, silica fume is widely used in concrete, refractory materials, paint and other industries. High-quality microsilica fume can be used as an admixture for concrete to prepare high-strength concrete, such as high-strength concrete with a strength level of hundreds of MPa. In addition, silica fume can also be used to make hollow insulation panels for exterior wall insulation. Since hollow insulation panels made of silica fume are lighter, more energy-saving and thermally insulating, they have been widely used in the field of building energy conservation.

Although metallic silicon powder and silicon powder are both in the powder state of silicon, their composition, chemical properties, physical properties and uses are very different. Through in-depth understanding and comparison of these two types of silica powder, we can help people better choose products that suit their needs, thereby improving the efficiency and quality of industrial production and construction.
