A Comprehensive Guide to Calcium Metal in China
Calcium metal, a reactive alkaline earth metal, holds significant importance in various industries. China, a global leader in metal production, plays a crucial role in the supply and manufacturing of calcium metal. This guide delves into the intricacies of calcium metal production, its diverse applications, and the variations in its forms. We’ll explore the technical specifications and differences between various types of calcium metal available in the Chinese market.
The production of high-purity calcium metal, often exceeding 99.5% purity, is a key focus in China. Companies like Winfred International Metal Limited (www.winfredint.com) specialize in producing calcium metal in various forms, including irregular blocks and extruded wires. The manufacturing process usually involves multiple distillation techniques to achieve the desired high purity. This purity is crucial for applications demanding high-quality materials.
The applications of calcium metal are widespread and diverse. Its primary use lies in the steel industry, where it acts as a powerful deoxidizer, decarburizer, and desulfurizer. This significantly improves the quality and properties of alloy and special steels. Furthermore, calcium metal serves as a reducing agent in the production of high-purity rare earth metals. The pharmaceutical industry also utilizes this versatile metal in specific applications.
The choice of calcium metal form depends on the specific application. Granules, lumps, turnings, and wires are commonly available forms. Each form possesses unique characteristics that make it suitable for particular processes. Ruizhaoyang Metals (www.calciummet.com) offers a range of calcium metal products, including granules specifically for cored wire production. The size and purity of the calcium metal significantly influence its application.
Let’s compare the technical features of different calcium metal forms:
| Feature | Lumps | Granules | Turnings | Wire |
|---|---|---|---|---|
| Particle Size | 20-200mm (variable) | 0-7mm (variable) | Small, irregular | Consistent diameter |
| Surface Area | Relatively low | Relatively high | Relatively high | Relatively low |
| Reactivity | Moderate | High | High | Moderate |
| Handling | Easier | More difficult | More difficult | Easier |
| Typical Purity | 99.5% min | 98.5% min | 98% min | 98.5% min |
Now, let’s examine the differences between various types of calcium metal:
| Type | Purity (%) | Typical Form | Primary Applications | Supplier Example |
|---|---|---|---|---|
| High Purity Calcium | ≥99.5 | Lumps, Granules | Atomic industry, national defense, rare earth reduction | Winfred International Metal Limited (www.winfredint.com) |
| Regular Purity Calcium | ≥98.5 | Lumps, Granules, Turnings, Wire | Steelmaking (deoxidation, desulfurization) | Ruizhaoyang Metals (www.calciummet.com) |
| Calcium Alloys (Ca-Al) | Variable | Lumps, Granules | Lead-acid batteries, other metallurgical applications | Winfred International Metal Limited (www.winfredint.com) |
