### **I. Overview of Wollastonite Products**

Wollastonite (chemical formula: CaSiO₃) is a natural white needle-like mineral, mainly composed of silicon dioxide (SiO₂) and calcium oxide (CaO). Its unique crystal structure endows it with the following characteristics:

- **High whiteness** (up to over 90%), suitable for fields with strict color requirements;

- **High melting point** (about 1540°C), with excellent high-temperature resistance;

- **Low oil absorption**, reducing the formulation cost of products such as coatings and plastics;

- **High aspect ratio** (needle-like structure), enhancing the mechanical properties of composite materials;

- **Chemical inertness**, resistant to acid and alkali corrosion, with strong stability. 

Through refined processing (such as ultrafine grinding and surface modification), wollastonite can meet the customized demands of different industries.

### **II. Main Application Areas of Wollastonite**

1. **Ceramic Industry**

- Reduces firing temperature, shortens production cycle, and reduces energy consumption;

- Enhances the strength of ceramic bodies, reduces drying shrinkage and cracking;

- Used in glazes to increase gloss and wear resistance. 

2. **Coatings and Paints**

- As a functional filler, it improves the hardness, weather resistance and corrosion resistance of the coating;

- It can replace part of titanium dioxide, reducing raw material costs;

- It reduces VOC emissions, complying with environmental regulations. 

3. **Plastics and Rubber**

- Enhance tensile strength, dimensional stability and flame retardancy of reinforced products;

- Better compatibility with polymer matrix after surface modification;

- Applied in high-strength engineering plastics for automotive parts, electronic casings, etc. 

4. **Metallurgy and Refractory Materials**

- As a flux, it enhances the efficiency of metal smelting;

- It is used to manufacture high-performance refractory bricks, extending the service life of kilns. 

5. **Environmental Protection Field**

- Adsorption of heavy metal ions in wastewater treatment;

- Alkaline regulator for soil remediation.
