Microsilica powders (Microsilica) are usually available in different types according to their different production processes, particle characteristics and uses. The models of micro-silicon powder are mainly reflected in the following aspects:
Microsilica powder model
1. Sort by particle size
The particle fineness of micro-silicon powder is usually an important index to measure its performance. According to the particle size, microsilicon powder can be divided into the following types:
- Low ash type (low SiO₂ content) micro-silica powder: usually a coarser particle with a relatively low silicon content. This type of product is suitable for concrete or other building materials with low fineness requirements.
- Standard micro-silica powder: the particle size is generally between 0.1 micron and 1 micron, which is a common micro-silica powder model, suitable for most construction, rubber, casting and other fields.
- Ultrafine micro-silica powder: the particle size is less than 0.1 micron, has a larger specific surface area and higher activity, and is suitable for concrete, high-performance electronic materials and other fields requiring very high performance.

2. Classification by silica content
The silica content of micro-silicon powder is usually between 85% and 98%, and according to the different silicon content, micro-silicon powder can be divided into the following categories:
- High purity silica powder: the SiO₂ content is usually greater than 95%, this kind of silica powder has higher reactivity and physical properties, and is widely used in concrete, high-performance rubber, electronic components and other fields requiring high strength and high durability.
- Ordinary micro-silica powder: the SiO₂ content is about 85%-90%, which is suitable for general building materials and casting, rubber and other industries, and the cost is low.

3. Classified by surface modification
Some microsilica powder products are surface modified to improve their performance in specific applications, common types include:
- Surface activated micro-silica powder: This micro-silica powder through special surface treatment, such as chemical activation, surface coating, etc., to increase the compatibility with cement or rubber, improve its strengthening effect.
- Ultrafine treatment type micro-silica powder: By ultrafine treatment of particles, increase the specific surface area and improve the reactivity of micro-silica powder, which is often used in high-strength concrete or high-performance rubber and other fields.

4. Classified by production process
The production process of microsilicon powder will also affect its performance, common processes include:
- Desiliconization: The micro-silica powder obtained through the purification process has a lower impurity content, and is widely used in high-end concrete, coatings and electronic materials.
- Ferrosilicon slag method: By extracting micro-silica powder from ferrosilicon slag, it has a high cost performance and is suitable for large-scale applications, especially in construction, casting, rubber and other fields.

5. Categorize by use
There are also different models of micro-silicon powder for different purposes, which are mainly determined according to the performance requirements of the specific application. For example:
- Building grade micro-silica powder: This micro-silica powder is often used to strengthen concrete, and has good fluidity, strength, and impermeability.
- Rubber-grade micro-silica powder: specially designed for the rubber industry, micro-silica powder has good dispersion and strengthening effect.
- Casting grade micro-silica powder: used in casting sand, with good fluidity, formability and surface finish.

Examples of common microsilica powder product models
- SF100: Generally refers to high purity, fine particles, suitable for high-performance concrete and other fields.
- SF85: microsilica powder with about 85% SiO₂ content, suitable for ordinary building concrete.
- SF98: With a SiO₂ content of more than 98%, it has extremely high activity and is suitable for high-strength, high-durability concrete or other engineering applications.
- SF120: Used in special engineering, such as solar cells, fuel cells, micro silicon powder, usually very fine particles, high surface activity.
Microsilica powder model
There are many models of micro-silicon powder, and it is important to choose the right model according to the specific application. In the selection, in addition to considering the particle size and silica content of micro-silicon powder, it is also necessary to pay attention to its surface treatment, production process and other characteristics. Different types of micro-silica powder have their own advantages and applications in concrete, rubber, casting, electronics, energy and other fields.
