Overview of High Purity 99.99% Ultrafine Metal Indium Powder

High Purity 99.99% Ultrafine Metal Indium Powder comprises a broad category of finely divided, solid particles derived from various metals or metal alloys. These powders exhibit unique characteristics that make them indispensable in modern manufacturing and advanced technologies.

Key Characteristics of High Purity 99.99% Ultrafine Metal Indium Powder

  1. 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.

  2. 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.

  3. 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.

  4. 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 High Purity 99.99% Ultrafine Metal Indium Powder

Indium is a chemical element with the symbol In and atomic number 49. Ultrafine metal indium powder with a purity of 99.99% typically has the following parameters:

1. **Purity**: As stated, the purity is 99.99% or 4N (four nines), indicating that there are less than 0.01% impurities present in the powder.

2. **Particle Size Distribution**: Ultrafine refers to the extremely small particle size, usually measured in micrometers (μm) or nanometers (nm). For high purity indium, the particle size may range from around 50-200 nm for ultrafine powders.

3. **Crystal Structure**: Indium naturally forms a face-centered cubic (FCC) crystal structure, which means the powder particles will have this same arrangement.

4. **Melting Point**: Indium has a melting point of approximately 156.6°C (314°F) under standard pressure.

5. **Density**: The density of pure indium is 7.31 g/cm³ at room temperature.

6. **Chemical Properties**: Indium is highly reactive and readily forms an oxide layer on its surface when exposed to air. It reacts with halogens (like chlorine and bromine), sulfur, and some acids.

7. **Thermal Conductivity**: Indium is known for its exceptional thermal conductivity, which is about 45 times that of copper, making it useful in heat sink applications.

8. **Electrical Conductivity**: Indium has excellent electrical conductivity as well, making it a key material in semiconductors and electronic devices.

9. **Storage Requirements**: Due to its reactivity, indium powders should be stored in a dry, inert atmosphere, often in an airtight container lined with an indium-tin oxide (ITO) film or another protective coating.

10. **Applications**: Ultrafine indium powder finds applications in various industries, including electronics (thin-film transistors, solar cells), optoelectronics, aerospace, and microelectronics due to its unique properties like high thermal and electrical conductivity.

Please note that specific parameters may vary depending on the supplier and manufacturing process. Always consult the product data sheet for detailed information.

FAQs of High Purity 99.99% Ultrafine Metal Indium Powder

Q1. What exactly is High Purity 99.99% Ultrafine Metal Indium Powder , and how is it different from solid metal?

High Purity 99.99% Ultrafine Metal Indium Powder consists of tiny particles of pure metals or metal alloys. Unlike solid metal, which exists as a continuous mass, metal powder offers increased surface area, making it more reactive and easier to form into complex shapes through processes like sintering or 3D printing.

Q2. How is High Purity 99.99% Ultrafine Metal Indium Powder produced, and what are the common production methods?

High Purity 99.99% Ultrafine Metal Indium Powder is typically produced through several methods, including:

– Atomization: Molten metal is sprayed into fine droplets that cool and solidify into powder.

– Chemical reduction: Metal oxides are reduced to their elemental state to form powder.

– Electrolysis: Electrical current is used to deposit metal onto a cathode, later harvested as powder.

– Mechanical processes: Large metal pieces are milled or ground down into powder.

Q3. What factors determine the quality and suitability of metal powders for different applications?

Quality and suitability depend on factors like:

– Particle size and distribution: Affects flowability, packing density, and final product properties.

– Composition and purity: Determines the material’s properties and its appropriateness for specific uses.

– Shape: Spherical powders for better flow, flake shapes for coatings.

– Density and porosity: Influences strength and other mechanical properties.

Q4. What safety precautions should be taken when handling metal powders?

Safety measures include:

– Wearing personal protective equipment (PPE) like gloves, goggles, and respirators.

– Storing powders in airtight containers away from moisture, heat, and ignition sources.

– Using explosion-proof equipment in processing areas.

– Ensuring proper ventilation to avoid dust accumulation and inhalation risks.

– Following strict handling procedures to prevent spills and cross-contamination.

Q5. How are High Purity 99.99% Ultrafine Metal Indium Powder used in the manufacturing industry?

High Purity 99.99% Ultrafine Metal Indium Powder find applications in:

– Powder Metallurgy: To create parts by compacting and sintering, ideal for mass production of complex components.

– Additive Manufacturing (3D Printing): Layer-by-layer construction of parts for customized and intricate designs.

– Thermal Spray Coatings: Applying protective or functional coatings to surfaces for corrosion resistance, etc.

– Electronics: Precious metal powders in conductive pastes, connectors, and other components.
