DESCRIPTION
High-density silicon powder refers to finely ground particles of silicon with an increased density compared to regular silicon powder. This is achieved by a specialized process of compacting, sintering, or alloying the silicon particles to form a more tightly packed and uniform product.
High-density silicon powder has several unique properties and applications. It has a high melting point, good thermal conductivity, and can be used in manufacturing semiconductors, solar panels, and electronic devices. It is also used as a reagent in chemical manufacturing, and in the production of refractories and ceramics.
The increased density of the powder allows for better packing of the particles, resulting in a higher surface area and greater reactivity with surrounding materials. This makes high-density silicon powder an excellent additive for high-performance composites, such as sintered ceramics, metal matrix composites, and polymer composites.
