Overview of Silicon metal lump powder granule high quality silicon metal
Silicon metal lump powder granule high quality silicon metal 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 Silicon metal lump powder granule high quality silicon metal
-
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 Silicon metal lump powder granule high quality silicon metal
Silicon metal (Si), also known as ferrosilicon or silicide, is an important metallic alloy used in various industries due to its unique properties. Here are some key parameters for high-quality silicon metal:
1. Chemical Composition:
– Pure Silicon (Si): Typically, the purity of high-quality silicon metal ranges from 98% to 99.99% Si, with very low impurities like carbon (C), oxygen (O), and iron (Fe).
2. Particle Size and Form:
– Lumps: The size can vary, but usually, high-quality silicon metal lumps range from 50mm to 200mm in diameter.
– Powder: Particle sizes may range from sub-millimeter to a few millimeters, suitable for use in fine powders or as a precursor in chemical processes.
– Granules: These are intermediate-sized particles, typically around 1 to 5 mm.
3. Purity Standards:
– SGML (Silicon Metal Grade Limit): A standard grading system defines different grades based on impurity levels, such as SGML-1 (highest purity) to SGML-6 (lower purity).
4. Hardness and Melting Point:
– Hardness: Silicon metal is relatively soft, having a Mohs hardness of about 6.5-7.
– Melting Point: It has a melting point of approximately 1,414°C (2,577°F).
