Key Characteristics of Further-Chemical High purity 99.99%min Sc Scandium metal powder CAS 7440-20-2
-
Particle Size and Distribution: The size and uniformity of particles significantly influence flowability, packing density, and the final product’s mechanical and physical properties. Finer powders generally offer a larger surface area, which is beneficial for reactions and sintering but may also increase aggregation.
-
Composition: Metal powders can be elemental (pure metal) or alloyed, combining two or more metals to achieve desired properties such as enhanced strength, corrosion resistance, or electrical conductivity.
-
Shape: Particle shapes range from spherical to irregular or flake-like. Spherical powders provide better flowability and packing, while flake-shaped powders are suited for coatings and electronic applications due to their unique orientation and surface area.
-
Purity: Depending on the application, metal powders can be highly purified to remove impurities, critical for uses in electronics, aerospace, and medical devices where contamination could compromise performance.

Parameters of Further-Chemical High purity 99.99%min Sc Scandium metal powder CAS 7440-20-2
Scandium (Sc), also known as Element 21, is a chemical element with the symbol Sc and atomic number 21. It belongs to the lanthanide series in the periodic table but is often grouped with the transition metals due to its similar properties. Scandium metal powders, specifically the high purity 99.99%min variety, have a CAS number 7440-20-2, which is the unique identifier assigned by the Chemical Abstracts Service.
Here are some key parameters for this high purity Scandium metal powder:
1. **Purity**: 99.99% min – This indicates that the product contains at least 99.99% pure scandium metal, with impurities present at or below 0.01%.
2. **Form**: Metal powder – The material is in the form of fine particles, which can be easily mixed and used in various chemical applications.
3. **Appearance**: Silver-gray or silvery-white in color – Scandium has a metallic luster, typical of most metals.
4. **Melting Point**: 1814°C (3305°F) – This is the temperature at which the solid scandium metal begins to melt and change into a liquid phase.
5. **Boiling Point**: 3690°C (6674°F) – The temperature at which it starts to boil and turn into a gas.
6. **Density**: 2.98 g/cm³ – Scandium has a relatively low density compared to other transition metals, making it lightweight.
7. **Hardness**: Moderately hard – It’s harder than pure iron but softer than most other transition metals.
8. **Reactivity**: Scandium is moderately reactive and can react with oxygen, halogens, and some acids at elevated temperatures.
9. **Applications**: High purity scandium metal powder finds use in aerospace, nuclear reactors, electronics, alloys (e.g., Sc-Al alloys for high-temperature applications), and as a catalyst in certain chemical reactions.
10. **Storage**: It’s important to store scandium metal powder in an airtight container to prevent oxidation and maintain its purity.
Please note that handling and safety precautions should always be observed when working with high purity metals like scandium, as they can be reactive and toxic if not handled properly.
