What Are Calcium Metal Granules?
Calcium metal granules are small, solid pieces of pure calcium, typically created through cutting or grinding larger pieces of calcium metal. The granules come in various sizes and purities, with the most common being 99% pure or higher. These granules are highly reactive, especially in the presence of moisture or oxygen, making them valuable in a variety of chemical and industrial applications.
Key Properties of Calcium Metal Granules:
- Purity: Typically ranges from 98.5% to 99.9% purity.
- Size: Available in various sizes, from fine powders to large chunks, though granules are typically around 1-5 mm in size.
- Reactivity: Calcium reacts readily with oxygen and water, making it useful in specific chemical processes.
- Appearance: Shiny metallic with a bright luster when freshly cut.
Types of Calcium Metal Granules
1. High Purity Calcium Granules (99%)
High-purity calcium granules, such as those offered by companies like Noah Chemicals and Amertek, are designed for sensitive industrial applications and laboratory research. These granules exhibit minimal impurities and are primarily used in research, where precise chemical reactions are necessary.
2. Standard Calcium Granules (98.5%)
Granules with a purity of 98.5%, like those sold by HSALLOY LIMITED and Met India, are more common in industrial settings. These are used for alloy production, desulfurization in steelmaking, and other high-temperature processes. While they are less pure, they still provide the desired reactivity and performance in industrial applications.
3. Bulk Calcium Granules
Bulk calcium granules, such as those from ZX Ferroalloy, are typically used for large-scale manufacturing processes. These granules are packaged in larger quantities and are suitable for high-demand applications, such as metal production and the creation of specialized alloys.
